Gas detector PS2x4C2-A-U-S1.5-2-M1/D5

ethanolmethanolinfrared

The pyro-detector measures methanol (CH4O/half structure formula: CH3OH) & ethanol (C2H5OH) at ambient temperatures between -20 and 85 °C. With its high detectivity of up to 4.0*10^8 cm√Hz/W and a sensitivity of up to 200000 V/W, the 2-channel detector represents the high end solution for demanding applications in medical or industrial production and process applications. The optical filter with a CWL of 9663 ± 80 nm and a HBW of 240 ± 40 nm combined with the reference channel are specially designed to analyze typical alcohol compounds. The exceptional signal values result from the combination of a broad spectral sensitivity of 2 - 15 µm (optimized from 3 - 5 µm), a high sensitivity with a modulation frequency of up to 100 Hz, a low microphone effect due to the low membrane mass, very low temperature dependence and an amplified signal in current mode. The reliable measurement results are furthermore secured by a high read-out rate up to 100 Hz as well as by the short response time.
