It can be set to automatically overwrite data or not to overwrite data when the capacity is insufficient, and automatically stop recording.


●The standard infrared remote control can realize the operation without opening the cover in dangerous situations, such as: modify the alarm point, concentration calibration, zero point calibration, silence, restore the factory, enter the menu, view the record, 4mA output, 20mA output (calibrate other acquisition equipment) This function is required).


●Chinese and English interface can be selected, the default Chinese interface, support free switching of gas concentration units, conventional gas does not need to enter the molecular weight, and the molecular weight of special gas is automatically calculated and switched after entering the molecular weight. The units are optional: PPM, mg/m3, Vol%, LEL% , PPHM, ppb, mg/L


●The 2.5-inch high-definition color screen (LCM) displays real-time concentration, time, temperature, humidity, storage status and other information, and can simultaneously detect 1 to 6 gas concentrations and temperature and humidity. The menu interface uses high-definition simulation icons to display the function names of each menu , Concise Chinese or English operation prompts.


●Three display modes can be switched: simultaneous display of multiple gas concentrations, large font cycle display of single channel gas concentration, real-time curve, automatic or manual cycle between channels can be switched, you can set whether to display the maximum value, minimum value, gas name , You can view the historical record graph.


●Automatically track the zero point to prevent drift, temperature compensation, multi-level calibration, which can simultaneously meet the national standard and the standards of the local and provincial metrology bureaus in various regions


●Data recovery function, automatic identification and prevention of incorrect operation of concentration calibration, which can avoid defects caused by improper operation.


●Can record calibration log, maintenance log, troubleshooting countermeasures, reminder of the expiration of sensor life, reminder of the next concentration calibration time
