Portable NH3 Gas Detector Item:MS104K-L-NH3 Portable Gas Detector General Description: MS104K-L portable gas detector is mainly used for rapid and accurate detection of gas leakage or gas concentration exceeding the alarm. The main detection principles of gas detection are: electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoionisation, etc. MS104K-L is widely used in fire fighting, emergency rescue, restricted space, petroleum, chemical, metallurgy, refining, gas, storage, medicine, environmental protection, air treatment and other occasions. Features: Built-in pump suction measurement, can be switched to diffusion, diffusion + pump suction detection. Pump clogging alarm LED lighting (optional) Unit free switching, unit optional: umol/mol, ppm, pphm, ppb, mg/m3, ug/m3, %Vol, %LEL 8 button operation, quick one-key calibration function Data storage, storage capacity of not less than 100,000 items Communication interface: TYPE-C, option: Bluetooth Fall alarm Data recovery function, partial or full recovery of factory data Maximum value, minimum value, weighted average value display Multiple alarm mode alarm mode setting: Alarm mode: sound and light alarm, vibration alarm, voice alarm Alarm type: Concentration alarm, under pressure alarm, fault alarm, pump blockage alarm. Alarm mode: low alarm, high alarm, interval alarm, TWA/STEL alarm Misoperation identification function, concentration calibration misoperation is automatically identified and prevented Zero point auto-tracking, avoid zero point drift Multi-level calibration of target point Intrinsically safe circuit design, explosion-proof, shock-proof, anti-static, anti-radiation Protection level IP68, rain and soak-proof, dust-proof, anti-corrosion Technical Parameters: Detection Gas Ammonia NH3 Detection range NH3:0-300ppm Resolution 0.1ppm Unit Display umol/mol,ppm,pphm,ppb,mg/m3,ug/m3,%Vol,%LEL(Optional) Detection Principle Electrochemical Sensor Life 2-3 years Detection method Built-in pump suction type, can be switched to diffusion, diffusion + pump suction detection mode Display LCD Linearity ≤±3% Repeatability ≤±2% Response time T90≤20s Recovery time ≤30s Operating power DC3.7V*2 Battery capacity 2500mAH rechargeable polymer battery with over-charging, over-discharging, over-voltage, short-circuit and over-heating protection.
