Product Description

MS104K-L Single Gas Detector




All the cases require the portable rapid detection of gas concentrations such as petroleum, chemical, pharmaceutical, environmental protection, combustion gas distribution, warehousing, smoke gas analysis, air governance, and so on.


The main functions of MS104K-L portable gas detector are for The main functions of the MS104K-L portable gas detector are to quickly and accurately detect gas leaks or gas concentration exceeding the alarm limit. The main detection principles of gas detection are: electrochemical, infrared, catalytic combustion, thermal conductivity, PID photoionization, etc. The MS104K-L is widely used in firefighting, emergency rescue, confined space, petroleum, chemical industry, metallurgy, refining, gas, storage, medicine, environmental protection, air treatment and other occasions.




● Built-in pump suction measurement, can be switched to diffusion, diffusion + pump suction detection mode

● Pump clogging alarm

● LED lighting (optional)

● Unit free switching, unit optional: umol/mol, ppm, pphm, ppb, mg/m3, ug/m3, %Vol, %LEL

● 8-key operation, quick one-key calibration function

● Data storage, storage capacity of not less than 100,000 items

● Communication interface: TYPE-C, option: BluetoothFall alarm

● Data recovery function, part or all of the factory data recovery

● Maximum value, minimum value, weighted average value display

● 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 recognition function, concentration calibration misoperation is automatically recognized and blocked

● Zero point auto-tracking, avoiding zero point drift.

● Multi-level calibration of target point

● Intrinsically safe circuit design, explosion-proof, shock-proof, anti-static, anti-radiation.

● Protection class IP68, rain and immersion, dustproof, anticorrosive




It is widely used in areas where explosion-proof is required or toxic gas leaks, like underground channels or the mining industry, so as to protect the worker's life and avoid damage to the relevant equipment.
