New Compact Tdl Oxygen Analyser For Hazardous Areas

Neo Monitors AS (Norway) launches with the LaserGas III Single Path (SP) for O₂ its 3^rd generation of LaserGas analysers. This new oxygen analyser is specifically designed for operation in hazardous areas. The entire instrument is built into compact flameproof enclosures making it fit for zone 1 and division 1 applications without any purge.

The highly selective laser source operating at room temperature scans the single gas absorption line specific to oxygen, thus eliminating cross interference from other gases. A detector located opposite the laser detects the light absorption caused by the oxygen molecules, after which the gas concentration is calculated. Transmission changes caused by varying dust load do not interfere with the measurement. Automatic correction for process temperature and pressure variations is included.

Focused applications are inertisation control of reactors, tail gas treatment, and flare gas monitoring in the chemical and petro-chemical industry as well as off-gas analysis in incinerators and furnaces in the minerals & metals industry. The LaserGas III O2 is the solution for reliable and fast measurement of oxygen in corrosive, dusty, sooty gas mixtures and in gas mixtures that contain condensates or tar. Process gases may be measured up to 10 bar pressure and 1500 ^oC temperature. A spectroscopic temperature measurement utilizing the same laser source is available as option.
