1 GENERAL USER INFORMATION
1.1 LGD F200P2 introduction
Axetris’ laser gas detector (LGD), “LGD F200P2,” is a system for the continuous monitoring of gases such
as NH
3
and (H
2
O), HCl and (H
2
O), CH
4
or CO
2
. Based on state-of-the-art Tunable Diode Laser
Spectrometry (TDLS), the system has a very high selectivity to the target gas and features an innovative,
patented measurement principle without the need for a physical reference channel. The system is based
on a flow-through cell for extractive gas measurements and exists in two versions:
i) A-version: For the measurement of gases at ambient (A) temperature (pictured on right in Figure 1).
ii) H-version: For hot-gas measurements (H) typically at 190°C, slightly bigger due to heater & insulation
(pictured on left in Figure1).
Typically one system monitors one gas. Concentration
ranges are customer-specific and can cover 0-10 ppm just
as well as 0-100 percent, depending on the gas and
measurement conditions.
Calibration is factory set according to customer application
requirements—generally re-calibration is not necessary
except in cases where the customer application conditions
differ significantly from the feasible factory calibration
conditions. Offset and span adjustments can be performed
on a maintenance basis and might be necessary due to
systematic differences in calibration and gas delivery
equipment. This can be done via the Graphic User
Interface (GUI) provided with the system software.
