The main function:
◆ Unique LCD with backlight design technology can display measurement information under any lighting conditions;
◆ Support PPM and mg/m3, %VOL and mg/L concentration units to switch freely;
◆ The gas chamber is made of military-quality high-strength aluminum profile, which is wear-resistant and corrosion-resistant, and is suitable for complex and harsh industrial environments. The reasonable and scientific design of the gas chamber ensures the accuracy of real-time monitoring of the sensor;
◆ The short-distance RTU wireless transmission method or the GPRS wireless transmission method with unlimited distance anywhere can transmit real-time detection data and alarm status to the safety center through the built-in wireless module function (optional) ;
◆ The explosion-proof grade is Exd II CT6, certified by the National Explosion-proof Electrical Inspection Center.
