Technology Used
The following instrument configurations are available in the 2900 LaserGas II product line:

- Single Path monitor
- Single Path compact
- Open Path monitor
- Multipass monitor

Single Path monitors are mainly used for in-situ measurements with path lengths in the range 0.5 – 15m (pipes, stacks, ducts). These models operate with samples in range 2-3 bar maximum pressure and temperatures up to 500°C. It is possible to measure samples at up to 20 bar and 1500°C with some gases. The additional feature of automatic zero and span check can be supplied as an option.

The Open Path monitor is suitable for long distance monitoring in ambient air, monitoring of production halls, gas fencing or leak detection. Measurement lengths of up to 1000m are possible. Gas detection is unaffected by dust and smoke or fog and rain down to <1% transmission.

The extractive Multipass monitor allows a gas sample to be removed from the process and analysed offline. Based on multiple reflections in the analysis cell, this instrument combines 11 m measurement path with a very compact design and is suitable for trace measurements of, for example, H2O, O2 or H2S.

Please refer to the relevant Servomex product data sheets for more information on the different instrument configurations.


Features
Designed for continuous monitoring, LaserGas II models offer high sensitivity with detection limits in the ppb and low ppm ranges.
Fast response times of down to one second are possible depending on the specific application. The range includes models for measuring O2, HCl, HF, NH3, CO, CO2, H2O, H2S, HCN, NO, N2O, CH4 and other hydrocarbons, as well as for measuring two different gases or a gas and temperature simultaneously using a single laser.
Compact and robust instruments suitable for outdoor use (protection classified to IP66)
Ethernet connector to enable communication via a local area network or the internet.
Ability to be fully configured to customers needs and tuned to the specific process. Ensuring optimum performance and zero cross interference from other gases present.


Typical Applications
LaserGas monitors are used for continuous emission monitoring and process control across a wide range of industrial applications e.g. in steel, aluminium and other non-ferrous metal, chemical, petroleum and cement production, marine operations, power generation and waste incineration.
Emission control systems for scrubber and abatement plants.
Combustion control systems for boilers and waste incinerators.
Slippage control in deNOx plants.
Safety systems in chemical plants.
Monitoring of production halls.
Gas fencing, leak detection.
Trace measurements in pure gases.
