Sensor Inlet
Where gas is measured. Keep it clean
and do not puncture the membrane.
LED Indicator Lights
These red lights will flash when the gas
concentration is high enough for an alarm.
There are four lights around the LCD.
LCD Display
Shows gas concentration from
0 -1,999 parts per million for CO and
0 - 400 parts per million for H2S
Power / MUTE Button
Press & hold to turn the power ON or OFF.
Press to mute the buzzer for up to 5 Minutes.
Buzzer / Speaker
Makes a beeping sound when an alarm
is active. Do not puncture the membrane.
Warranty
Each Inspector comes standard with a two year warranty
on all of its parts. It is recommended that you calibrate the
Inspector every six months to ensure the best accuracy
possible. An EOL (End of Life) symbol will display on the
LCD after two years of use. A successful calibration will
remove the EOL notification for an additional 180 days.
Future successful calibrations can continue to be done as
long as the electrochemical sensing element remains in
good condition.
Maximum Operating Conditions
Temperature: -20°C to +50°C (-4°F to +122°F)
Humidity: 20-90% R.H. (0-99% intermittent)
Practical Considerations
Short-term measurements (i.e. <1hr) in any humidity
(0-99% R.H.) are fine as long as condensation does not
block the sensor inlet. Longer term exposure to extreme
humidity or temperature outside the specified range can
result in damage to the sensor. Please note that the LCD
display and sensor will not function properly at colder
temperatures outside of the specified operating range.
NOTE: Exposure to higher temperatures
and humidity can damage the device.
