The detector utilizes electrochemical type and catalytic combustion type principles depending on the installed sensor type.
To ensure high detection accuracy, the device should be calibrated regularly, with the calibration interval not exceeding one year.
The detector runs on a DC3.7V lithium battery with a capacity of 2000mAh, offering a standby time of more than 8 hours and a charging time of 6 to 8 hours.
The detector should be stored in a well-ventilated room at temperatures between -10℃ and 55℃, with relative humidity not exceeding 85%RH, free from corrosive gases or impurities.
No. You must not disassemble, replace, or charge the battery pack in explosive gas environments. Replacing sensors or using plug-in devices without explosion-proof certification in such environments is strictly prohibited.
The standard kit includes one packing box, one portable single gas detector, one charger, one user manual, and one warranty card complete with a certificate of conformity.
