Description Overview GAOTek explosion proof gas detector is a high-performance fixed gas detector developed by our company, which is used for long-term continuous monitoring of combustible toxic and harmful gases in the air. It can continuously detect max 4 kinds of gas and display in real time, detect gas concentration by Natural diffusion. The standard 4 gases are CO O2 H2S and combustible gas, other gas can be combined flexibly. Features Detection accuracy, range adjustable, 4 mA to 20 mA protocol and 485 protocol Long life, high sensitivity, low drift, stable and reliable work Sensor fault self-check, two-level concentration alarm, with relay output function LCD gas concentration digital display and working state display With temperature compensation, automatic zero point correction function Infrared remote control mode, the detector can be adjusted without opening Explosion proof, Water Poof, and Dust Proof Technical Specifications: Battery DC 24 V ±10% Working Environment 15% RH to 90% RH (No condensation) Detection Principle Catalytic or electrochemical or infrared Alarm Method Light or sound Sampling Natural Diffusion Resolution 1% lel 1 ppm or 0.1 ppm Measurable Gas Flammable, toxic, harmful gas Applications Chemical plants, mines, oil refineries, pharmaceutical plants, metallurgical plants, gas stations, liquefied gas stations, brewing, hotel kitchens Measure Range And Resolution EX:0% lel to 100% lel, 1% lel O2:0% to 30% vol 0.1% vol CO:0 ppm to 2000 ppm, 1ppm or 0 ppm to 1000 ppm, 1ppm H2S:0 ppm to 200 ppm, 1ppm Feature Support a variety of gas customization (customized diversified products according to different industrial and mining) Output Signal RS 485 digital or Two bus wire Explosion-Proof Number CE10 1084 Explosion-Proof Marks Exd II CT6 Control Signal Switch output, the maximum load 250 V AC 3A(optional) Temperature -4 °F to 122 °F (-20 ℃ to 50 ℃) Size 8.66 in × 7.48 in × 3.54 in (22 cm × 19 cm × 9 cm)
