• Data recovery function: It can be selectively recovered or recovered completely, and the misoperation of concentration calibration can be automatically identified and prevented.
• Zero point automatic tracking, multi-level calibration of target point, improve the linearity and accuracy of measurement, and waterproof, dustproof, explosion-proof, shockproof.
• The three display modes can be switched, and the historical record graph can be viewed. The unit can be switched freely, and the unit can be selected: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.
• It adopts 10000mAh high-capacity rechargeable polymer battery, which can work continuously for a long time. Built-in pump suction measurement, fast response, sampling distance greater than 10 meters.
• The gas analyzer adopts a 3.5-inch high-definition color screen to display the concentration in real time, and three display modes can be switched. ·It can detect the gas concentration in the analysis pipeline or confined space and atmospheric environment, and can also detect gas leakage.
