Notice Regarding Sulfuryl Fluoride
Sulfuryl Fluoride is an odorless gas that has no warning properties. There is a danger of serious damage to
health by prolonged exposure through inhalation.
The SF-ExplorIR™ Monitor provides accurate, real-time sulfuryl Fluoride concentration measurements.
Only qualified and trained operators are, with proper use of the SF-ExplorIR™ Monitor, able to re-
enter and provide final clearance of fumigated spaces.
The SF-ExplorIRTM Monito is a continuous read and continuous motion clearance device per SF
label requirements.
Principal of Measurement
The Spectros Instruments Sulfuryl Fluoride (SO2F2) Clearance Monitor (SF-ExplorIR™) is designed
to detect, quantify and display the concentration of SO2F2 gas in the area being monitored.
The SF-ExplorIR ™ monitor uses non-dispersive infrared (NDIR) technology to detect low level
concentrations of sulfuryl fluoride and allows the final clearance and safe re-entry of fumigated spaces. The
concentration of sulfuryl fluoride is calculated according to absolute Laws of Physics. The calculation
compares a reference sample “zero air” (clean air in the internal air bag) against a sample reading.
Operation of Monitor
During normal operation the SF-ExplorIR™ displays both the current gas level and the peak gas level
detected on its front panel LCD. The monitor retains a log of previous readings that can easily be accessed
at a later time for analysis. Front panel indicators and an audible alarm are provided to signal gas alarm
and instrument fault conditions.
Aeration and Re-entry
Fumigators who are re-entering fumigation and risk areas to check for sulfuryl fluoride gas concentrations
must wear SCBA (Self Contained Breathing Apparatus) for respiratory protection until the concentration
within the structure has been confirmed to be 1 ppm or less. Please consult appropriate gas manufacturer’s
labels, state, and federal requirements.

iv
Correct Re-Zero Operation
The “zero air” sample needs to be of the same temperature and
relative humidity as the air to be measured for sulfuryl fluoride.
Purging the SF-ExplorIR™ after warm-up with previous held air inside the monitor is not the same as
forcing a Bag Empty and refilling with clean air known to be free of SF.
In cases where the monitor is taken from a cooler (air conditioned environment and set to work; the end-
user should empty the internal air bag content prior to use and refill with a know clean air sample at the
same temperature and relative humidity as the sample area to be measured.
Please consult operation manual and/or distributor for this procedure.
Notice for First Time Use of Battery
The SF-ExplorIR™ monitor is shipped with a partially charged battery and should be charged by the end-
user for at least 2 continuous hours prior to first use. If after this time the green LED’s are not observed
then depress the TEST button on the battery pack and hold until they appear. Repeat if necessary.
Compliant Battery
Spectros Instruments has determined and set the correct voltage and polarity needed for compliant battery
performance. Only a Spectros Instruments provided battery should be used. Use of another battery will
automatically void any warranty and may result in severe damage to the monitor.

Working with the DIAG Function
SILENCE – Sets the length of time the internal audible alarm is turned OFF
when the front panel SILENCE button is pressed. The factory default is 30
seconds. If the cause of the gas-alarm has not been cleared at the end of this
time period, the internal audible alarm will reactivate. Use the Keypad to
enter the desired time period, and then press ENTER to save that value and
return to the previous screen.
P-CHK – The Pressure Check function displays the current manifold
pressure and the stored ambient pressure in psia, along with the difference
between these two pressures and the current fault code. Refer to the heading
Working with the P-CHK Function on Page 17.
CLOCK – Sets the monitor’s date and time. Use the Keypad to enter the
correct date and time, and then press ENTER to save those values and return
to the previous screen. Note that time is displayed in a 24 hour format, while
the date is displayed as mm/dd/yy.

Leak Detector Operation
The monitor can be configured to operate as a Leak Detector by setting the AUDALRM function to LEAK
DETECTOR.
When configured as a Leak Detector, the monitor will produce a leak detector type of audible feedback. At zero
ppm there will be a tic every 2 seconds with the tic rate increasing up to 20 tics/second when the ppm level
reaches the ALRMLVL setting.
Standby Mode
After the monitor has been turned ON and allowed to warm up, the monitor can be placed into a Standby
Mode, ready for operation without waiting an additional 15 minutes before using. While in standby, the
monitor will stop taking gas samples and stop purging itself from the internal purge-air bag.
Place the monitor into its Standby Mode by pressing both the ENTER and ESC buttons at the same time.
Take the monitor out of standby by again pressing both the ENTER and ESC buttons.
When the monitor is taken out of standby, the operator must refill the purge-air bag by pressing the
ENTER button. Refilling the bag after coming out of standby re-establishes the monitor’s ambient pressure
reading and ensures that the purge-air bag is filled at the start of taking gas measurements.
WARNING: Fill the purge-air bag in a clean, fresh-air environment that is at the same
temperature and humidity as the area being check for gas. DO NOT fill the bag in an
area that is contaminated with sulfuryl fluoride gas.

As soon as the purge-air bag has been refilled with fresh air, the Data Display screen appears and the monitor
resumes normal operation.

Working with the Gas Alarm
Gas-Alarm Light
If the detected gas level reaches the gas-alarm level of 5 ppm, the monitor will detect this alarm condition
and turn ON the front panel ALARM light. The ALARM light will automatically turn OFF once the gas
level drops below 5 ppm.
Silencing a Gas Alarm
The monitor’s internal audible alarm will also activate when the gas level reaches the gas-alarm level.
Pressing the SILENCE button while the alarm circuit is activated causes the internal audible alarm to
turn OFF for a period of time as set by the SILENCE function. The front panel ALARM light will continue
to flash, however, as an indication that an alarm condition still exists. The audible alarm will reactivate at
the end of the silence period if the detected gas level is still above the gas-alarm level.
Silencing a Fault Alarm
The FAULT light and audible alarm will automatically turn OFF after the cause of the fault has been
eliminated.
Working with System Faults
Functional Overview
If a system malfunction occurs (see Fault Code list on Page 15), the monitor will detect the problem and
turn ON the front panel FAULT light.
The FAULT light will automatically turn OFF after the cause of the fault has been eliminated.
Viewing the Faults Log
From the Data Display screen, press both Keypad Left and Right buttons at the same time to display the
first Function Menu screen. Next, use the Keypad buttons to move the arrow (>) until it points to the
FAULTS function, and then press the ENTER button to display the Faults Log screen.
The Faults Log screen shows the monitor’s current fault status. If the fault
is still present when the FAULTS function is selected, then the current cause
of the fault is displayed along with the date and time it occurred. If the cause
of the fault has been cleared, then the Faults Log screen will show <0000>
along with the date and time the fault was cleared. Use the Keypad buttons
to scroll through the faults log. In the screens shown to the left, record #03
shows that a Sample Flow Fault (fault code <0800>) occurred on 07/11/15 at
08:17, while record #04 shows that the fault was cleared on 07/11/15 at 9:00.
The cause of the fault is identified by a numeric fault code. To convert the
fault code into a text description of the fault, first press the ENTER button
and then use the Keypad buttons to scroll through the display until the text
description of the fault appears. If the fault code is a combination of two or
more faults, then continue to use the Keypad buttons until all fault text
descriptions have been displayed. For example, the fault code <1800>
represents the combination of both a Sample Flow <0800> and a Purge Flow
<1000> fault as shown to the left.
The Faults Log can be cleared as described under the heading on Page 15.

Fault Codes
FAULT CODES ARE ADDITIVE. For example: A fault code of <0003> indicates that both a Box
Temperature Fault <0001> and a Bench Temperature Fault <0002> have occurred.
<0001> Box Temperature Fault: Enclosure temperature is outside normal range (or IR detector has
failed). Check that the monitor is not being subjected to extreme temperatures. Use the DIAG function to
check the Box Temperature.
<0002> Bench Temperature Fault: Optical bench is outside normal operating range (or IR detector has
failed). Check that the monitor is not being subjected to extreme temperatures.
<0004> Manifold Pressure Fault: The manifold pressure is outside its normal operating range (or IR
detector has failed). Enter the DIAG function and record ALL data. Call the factory with this information
for further instructions.
<0040> Fill Flow Fault: The purge-air bag’s pressure drop is outside expected limits. Check for a
punctured bag or disconnected tubing.
<0080> Over Range Fault: Monitor exposed to a gas level that exceeded 100 ppm.
<0100> Zero Filter Fault: The air-purge bag is contaminated with gas. Take monitor to a clean-air area
and use the EMTYBAG and FILLBAG functions to decontaminate the air-purge bag.
<0200> Gain Set Fault: The digipot autotune sequence has failed. This fault will only occur on first boot up
or after a firmware upgrade. Call the factory for further instructions.
<0400> A/D Fault: A fault has occurred in the analog-to-digital circuitry. Contact the factory with this
information for further instructions.
<0800> Sample Flow Fault: Check for: A restriction in the gas-sample inlet or exhaust; a blocked internal
filter; or a failed pump.
<1000> Purge Flow Fault: Check for: A restriction in the gas-sample exhaust; a blocked internal filter;
or a failed pump. Once the purge air stream has been restored, the monitor will return to normal
operation after it completes a purge cycle.
<2000> Bag Fill Fault: The purge-air bag did not fill within the expected time allotment. Check for a
punctured bag or disconnected tubing.
<4000> Zero Range Fault: The IR detector’s output voltage is out of tolerance. Enter the DIAG function
and record ALL data. Call the factory with this information for further instructions.
<8000> Clipping Fault: The detector voltage may be out of tolerance. Use the DIAG function to check the IR
detector voltage. Call the factory with this information for further instructions.
