Online-precision nitric oxide gas leak alarm

ST600N-line gas alarm, as natural diffusion Detection of gas concentration, the use of imported electrochemical sensors, catalytic combustion type sensors, infrared sensors or PID detector (to detect the type of gas: combustible gas and O2, H2S, CO, HCN, NO2 , SO2, NH3, HCL, CL2, H2 and other dozens of gas). Features ◆ alarm records query function ◆ detection accuracy, range adjustable ◆ long life, high sensitivity, low drift, stable and reliable ◆ sensor fault detection, two concentration alarms with relay output ◆ LCD or digital gas concentration digital display and work status display ◆ with temperature compensation, automatic zero calibration function ◆ 4 ~ 20mA standard analog output and RS485 digital output, you can upload DCS, PLC system ◆ Infrared remote control mode, no open can adjust the detector, safe and convenient ◆ use explosion-proof design for hazardous conditions, 1,2 Zone ◆ Technical data parameter detection principle: catalytic / electrochemical; ◆ Sample: natural diffusion; ◆ Display: 4 LED digital display concentration; ◆ Status Indicator : 3 LED lights indicate power, two alarm; ◆ debug mode: Infrared remote control; ◆ Ambient temperature: -20 ℃ ~ 70 ℃; ◆ Relative Humidity: <95%; ◆ Explosion-proof way: flameproof; ◆ Explosion-proof grade: Ex dⅡC T6 Gb; ◆ Power: DC24V ± 25%; ◆ Output signal: Current: (4 ~ 20) mA ◆ switch: 2 (two alarm normally open); ◆ Power: ≤3W; ◆ cable : ≥1.5mm2 × 3; ≥1.5mm2 × 4 ◆ The maximum distance between the detector and the host: ≤1000m; ◆ Total Weight: ≤1500g; ◆ pressure limit: 86kPa ~ 106kPa;
