SICK GM700 Gas Analyser – Laser Gas Analyser (Ammonia, Hydrogen Fluoride, Hydrogen Chloride)
In-Situ Gas Analysers
SICK GM700
The SICK GM700 in-situ laser gas analyser offers high reliability and precision as well as minimal response times. By using specific light absorption and Tunable Diode Laser Spectroscopy, or TDLS, the SICK GM700 is able to measure several gas components, such as NH3, HF, HCl or H2O.
In-situ gas analysers are ideal for quickly determining gas concentrations in process control and emission monitoring .
Fields of applications for the SICK GM700 include ammonia slip measurement in DeNox plants, emission monitoring of hydrogen fluoride in aluminium smelters, ammonia measurement in exhaust gas of combustion engines, ammonia measurement in composting or waste incineration plants, HCI measurement in combustion plants and HF measurement in the ceramics industry.Â

DeNOx
Selective Catalytic Reduction (SCR) is the process of NOx gas reduction, or DeNOx, that occurs when a NOx source is mixed with ammonia and allowed to react at the surface of the proper catalyst – the liquid ammonia injected upstream immediately turns into gas, mixes with the NOx gas and the mixture then reacts at the catalyst.
SICK GM700 Gas Analyser – Features
- High selectivity due to high spectral resolution
- Short response times
- No calibration required
- No moving parts: minimal wear and tear
- No gas sampling or conditioning required
- Overpressure encapsulated design for ATEX Zone 2
➡ Did you know? T&D also distribute SICK level sensors, flow sensors, pressure sensors and temperature sensors.
