Portable combustible gas tester

Portable combustible gas tester

Portable combustible gas tester is a mobile rapid detection of combustible gas concentration of compound gas detector, can detect up to 1 ~ 4 gases at the same time, with large capacity data storage function. Portable combustible gas tester uses 2.31-inch high-definition color screen to display real-time concentration, the selection of well-known brands of gas sensors, the main detection principles are: electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoion.

Features:

• Waterproof splash, dustproof, explosion-proof, shock-proof, intrinsic safety circuit design, anti-static, anti-electromagnetic interference,Passed national standard test and CMC measuring instruments production license certification
• Protection level IP65
• 2.31 inch HD color screen displays real-time concentration, alarm, time, temperature, humidity, storage, communication, power,Charging status and other information, the menu interface uses high-definition simulation ICONS to display the function name of each menu
• Large capacity data storage function, support 100,000 data storage capacity. Support real-time

Storage, timing storage, or only store alarm concentration data and time, support local view, delete data,The data can also be uploaded to the computer through the USB interface, and the data can be analyzed and stored and printed by the software of the upper computer.

• USB charging interface, overcharge, overdischarge, overvoltage, short circuit, overheat protection, 5 level *** power display
• The 2100mAH rechargeable polymer battery can work continuously for a long time
• Sound and light alarm, vibration alarm, visual alarm, undervoltage alarm, fault alarm, close alarm.
• Alarm value can be set, alarm mode can be selected low alarm, high alarm, interval alarm
• It can optionally detect 1 ~ 4 kinds of gas at the same time, and the unit can be switched freely

The unit can be PPM, mg/m3, Vol%, LEL%, PPHM, ppb, or mg/L

• Three display modes can be switched: display four gas concentrations at the same time, large font circulation display single-channel gas concentration, real-time curve, each channel

Between the automatic cycle or manual cycle can be switched, you can set whether to display the maximum value, minimum value, gas name, you can view the history.

• English interface is optional, default Chinese interface
• Data recovery function
• Zero automatic tracking, long-term use is not affected by zero drift.
• Multistage calibration
• Concentration calibration misoperation is automatically identified and prevented.
• Support OEM or ODM customization, RS485 communication can be optional
• Optional environmental temperature and humidity measurement function, more other functions or communication interface can be customized.
