GDM-2100 series special gas detector are mainly used in scenarios of toxic and harmful gas leakage detection in such industries as semiconductor, LCD panel, and photovoltaic industry. With fixed backplate mounting mode and pumping sampling method, they can detect over 40 toxic and harmful gases, including silane, phosphine, and ammonia.
Built-in sampling pump achieving quick response to gas leakage
Built-in microprocessorrealizing self-diagnostic
function
Smart box-type sensors, which can be calibrated in
an off-line manner
Magnetic front cover, avoiding the need of cover
opening tools, allowing for quick replacement of the sensor box and reducing the maintenance workload
Digital flow sensor, maintaining constant flow rate, reducing one-by-one check burden
Long-term stable quality and proven detection
