1 About the Lancom 200
This User Guide provides you with information on how to set up and use the
Lancom 200 Portable Acid Dewpoint Meter.
Lancom 200 is a portable analyser for measuring the Sulphuric Acid Dewpoint of
waste gases from combustion processes. The Lancom 200 Portable Control Unit
(PCU) provides comprehensive display, recording, calculation and output facilities
for monitoring and storing dewpoint readings and other data. These can be
printed out or transferred to a PC for further analysis.
The analyser has two main components: the Probe, and the Portable Control Unit
(PCU). The Probe is connected to the PCU by an air hose and an electrical cable.
The analyser requires a supply of clean, dry, compressed air. The minimum
supply pressure at the analyser is 4 bar (60 psi). The air ow rate may be
up to 350 l/min (12 scfm), so a minimum air hose bore of 13 mm (1/2 in) is
recommended.
Lancom 200 can operate from 230V or 110V ac supplies, or from its internal
batteries for up to 8 hours.
1.1 How does it work?
With the air valve on the PCU closed, the probe is inserted into the duct or ue,
and allowed to warm up. The air valve is then slowly opened to cool the probe
tip. Acid condensation is indicated by a rise in electrical current through the
sensor.
The rate of deposition of acid on the probe tip increases as its temperature is
lowered. If the cooling air ow rate is reduced, the probe tip warms up and
acid is evaporated off. At the Sulphuric Acid Dewpoint Temperature, the rate
of deposition and the rate of evaporation of the acid are the same, and the
lm thickness and current reading remain constant. A reading of 50µA on the
current meter has been found to correspond to a suitably thin lm of acid. The
temperature at which this reading remains constant is taken to be the Sulphuric
Acid Dewpoint Temperature.

3 Dos and Don’ts
Do...
When powering the equipment from the mains, use the supplied mains
lead. The mains supply outlet must include a protective earth terminal.
Beware of hot ue gas escaping from the measurement point !
Protect the probe tip from damage. When transporting the probe, always
t the protective cap, and avoid knocks or shock to the probe tip.
When operating the probe in a ue downstream of an electrostatic
dust precipitator take precautions to avoid the build-up of a hazardous
electrostatic charge on the probe and instrument. Either:
Operate the probe in contact with an earthed metal access ange, or
Operate the instrument on mains power (which provides a safe
discharge path to mains earth)
Use gloves when removing the probe from the ue as the probe body and
tip will be very hot. Allow the probe to cool before cleaning or stowing in
its bag.
When disconnecting the equipment, the air pressure in the hoses can
be released by isolating the air at the supply, then opening the air ow
regulator on the PCU for a few seconds.
Do not...
Do not operate the equipment for prolonged periods in direct sunlight or
high ambient temperature (greater than 50°C). Overheating may cause
failure of the electronics or premature shortening of battery life.
Do not operate the unit outside its carry case in wet conditions (rain or
spray).

6.2 Powering the Lancom 200
The Lancom 200 can be powered either by its internal batteries or from a mains
power supply (95 to 265 V a.c. ±10%, 50 to 60 Hz, 30 Watts).
The batteries in the Lancom 200 PCU will operate the unit normally for 8 hours
from fully charged. When the instrument is switched off, the batteries will keep it
ready for use for about 3 months, after which time it will shut down completely.
If the unit has been shut down, it will restart when the mains power is connected.
This will take about 15 seconds.
6.3 Charging the batteries
When mains power is connected, the batteries will be charged. The battery
charging light will ash when the power is rst applied; this means that the state
of charge of the batteries is being checked. The light will then change to Red
for boost charge or Green for trickle charge. The green light indicates that the
batteries are full.
If the Charge LED ashes red for longer than 2 minutes, remove the mains supply
and reconnect it after a few seconds. If the problem persists, the batteries may
need replacing. Contact Land Service.

Lancom 200 User Guide
Page 10
The battery level and the state of the battery charger can be viewed on the
System Data page. Note that the charging indication will icker for a few seconds
while the Red LED is ashing.
If the battery LED remains off when mains power is applied, then the batteries
are either too hot or too cold to be charged. Charging will commence when the
battery temperatures are within acceptable limits.
The Low Battery LED illuminates when there is enough charge left in the batteries
for about 1 hour of normal operation. If the unit is operated until the batteries
are completely exhausted, then the current Log File* may be lost. Switching the
unit off with the red button before the batteries go at will ensure that the Log
File is saved.
If the instrument does not switch on when the red button is pressed, the
batteries may be at. Connect a mains supply to the instrument and wait for it
to restart.
*Refer to Section 11 for information on Log Files.
Precautions when charging the battery
If the battery is being charged from at, ensure that there is adequate
ventilation around the instrument i.e. remove it from the carry case and
don’t charge it in an enclosed area.
If the battery charge LED does not go green (i.e. battery charged) after
8-10 hours, the battery may need to be replaced. Disconnect the mains
supply and contact the land service department.

7.2 Measuring the Sulphuric Acid Dewpoint Temperature
The Lancom 200 is congured such that is ready to measure acid dewpoint as
soon as the system components are connected and the unit is switched on.
The Lancom 200 probe is designed to t through a hole that is at least 50mm
(2in) in diameter.
Note
If you want to measure SO3 or H2SO4 you will need to set the water content
as accurately as possible. This is done via the Setup menu - refer to Section
10.1.
If you want to create a Toxic Release Inventory (TRI), you must rst input
the volumetric ow rate to be used in the calculation - refer to Sections 8.2
and 10.1
1) Close the air valve on the Lancom 200 Portable Control Unit (PCU) by
turning the knob on the front panel fully clockwise. Turn it gently until it
comes to a stop. Do not screw it down tight.
2) Ensure that the PCU is connected to a supply of clean compressed air.
3) Switch on the PCU by pressing the red power button.
4) When the red message screen appears, press the Enter key (on the right, in
the centre of the four arrow keys.)
The display should show two large dials. If it does not, then press the
Readings button (to the left of the X) until the dials appear.
4) Insert the probe into the stack or duct. It needs a hole that is at least
50mm (2in) in diameter. Block any gaps around the probe with cotton cloth
to reduce tramp air. Use the small knob in front of the probe handle to slide
the ue gas thermocouple out beyond the end of the probe.
5) Allow the probe to heat up to the ue gas temperature. The detector
temperature is shown on the right hand dial. The ue gas temperature is in
the bottom right corner of the screen. The left hand dial shows the sensor
current measurement. It may increase briey; then it should return to less
than 5µA. Wait until the readings are stable.
6) Increase the air supply slowly by turning the knob anti-clockwise. The air
ow rate is shown by the blue bar below the dials. This will get longer as
the air ow increases.
7) Increase the air supply until the detector temperature is dropping steadily.
Watch the left dial until its reading starts to increase. Reduce the air slightly
to slow down the rate of cooling. As the current reading increases, reduce
the air further. The objective is to hold the current reading at around 50µA.
8) When the current reading has been stable between 40 and 60µA for
about ve seconds, press the Enter button to record the Acid Dewpoint
Temperature (ADT). The message ADT Stored appears on screen.

9) If you want a paper record of the results, press the white printout button.
10) Close the air valve. Switch off the PCU by pressing and releasing the red
button.
Precautions to be observed after using the Lancom 200
Warning
The end of the probe will be VERY HOT after it has been in a ue or
stack.
1) Retract the ue gas thermocouple by pulling the small knob back against the
probe handle.
2) Remove the probe from the duct, taking GREAT CARE because the end of
the probe will be VERY HOT.
3) Allow the probe to cool before cleaning the sensor with a soft cloth and
replacing the probe in its carrying bag.

Lancom 200 User Guide

8 Additional monitoring and analysis options
In addition to the Sulphuric Acid Dewpoint Temperature measurement, the
Lancom 200 can be used to calculate the Rate of Build-up (RBU) and also
generate Toxic Release Inventories (TRI).
8.1 RBU (Rate of Build-up) calculation
The purpose of the Rate of Build-up (RBU)
measurement is to give an indication of the
severity of the corrosion which will occur at a
given temperature. RBU is measured in units of
µA/min.
The Lancom 200 plots a graph of RBU against
temperature, as shown.
Operation
Before calculating the Rate of Build-up, you must rst ensure that an Acid
Dewpoint has been recorded.
1) Use the Readings button to select the RBU display page.
The RBU screen displays the message Press Enter to start the RBU
sequence.
2) Press the Enter key.
Once the RBU sequence has started, the Readings key cannot be used to
navigate away from the RBU display. If you need to stop the RBU sequence,
press the Cancel button.
3) A marker will appear on the air ow bar graph, along with the Adjust
Airow message. Whenever this message appears, adjust the air control
knob until the air ow bar graph reaches the marker.
The system will rst try to heat the probe up until it is above the Acid
Dewpoint Temperature, then it will try to cool it at a steady rate. As it cools,
the graph will be created. If the Adjust Airow message appears, then
turn the ow control knob to bring the bar graph back to the marker.
4) If the probe cannot be heated up or cooled down sufciently, a warning
message will appear.
5) When the sequence is complete, the temperature at which the RBU is
greatest is displayed as Peak RBU Temp: xx°C. This is the temperature at
which corrosion will be most severe.
The RBU graph will be stored in a le called [RBU Data <date> <time> am/
pm.csv], in the same folder as the Log Files. The date and time format will
depend on the region setting. You can transfer this le from the Lancom
200 by using ActiveSync or a USB Flash memory device (Section 11).
