GD2R series gas detectors

New GD2R series gas detectors presents more sensitive ELECTROCHEMICAL sensor and having 2-stage alarm outputs make easy to create flexible automation according to the gas concentration in the medium.

Gas detector which incorporates electrochemical
sensor have 5 year sensor life under normal operating
condition, meaning that they have such stable
sensisitivity and high operating performance. When
gas concentration reaches to alarm threshold in the
medium, gas detector gives off visual and audial
warnings. Gas detectors have 2-level alarm output.
When the gas in the ambient reaches to the level of
50 ppm (parts per million), gas detector gets into
1st level alarm level. If gas concentration reaches
to the level of 200 ppm, then gas detector gets into
2nd level alarm. If gas concentration in the ambient
descends to 50 ppm, CO gas detector automaticaly
turns back to its normal operating condition.

AGD and GDR SERIES GAS DETECTORS

LPG and methane detectors
LPG (butane+ propane) and methane (natural gas)
are explosive hydrocarbon gases. The LPG and methane
detectors respond audibly and visually before the leakage
reaches 20% LEL (lower explosive limit)

Carbon monoxide (CO) detectors
Carbon monoxide is a toxic and explosive gas
The Mavigard carbon monoxide detectors respond audibly
and visually when the gas concentration reaches
50 ppm (parts of gas per million parts of air)

Ceiling type methane (natural gas) detectors
TGDR-1224M Ceiling type gas detectors have the same
apperance and dimensions of Mavigard fire detectors
Detector base also required for the ceiling type gas
detectors that is used for mounting
