Wired or wireless remote real-time monitoring can be performed, and data can be uploaded to a phone or transmitted to the Environmental Protection Agency, other monitoring centers, monitoring equipment, and monitoring computers via a local area network or the Internet.


Real-time monitoring of on-site concentration through PC software or gas alarm controller.


●Compatible with various secondary meters, data acquisition modules, PLC, DCS systems, can directly drive solenoid valves, fans, alarms and other equipment, and can also drive high-power equipment by driving intermediate relays.


Optional MIC3000 controller can monitor 1000 detectors at the same time.


●Large-capacity data storage function, can record real-time concentration value, temperature and humidity, or only alarm value and time.


Support local storage or SD card storage. The standard storage capacity of this machine is 100,000 records. If a larger capacity is required, please indicate when ordering.


SD card storage capacity can be customized. Data export and analysis through the host computer software, support to view or delete data on this computer, can be set when the capacity is insufficient


When the data is automatically overwritten or not overwritten, the recording function is automatically stopped.


●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 (this function is required to calibrate other acquisition devices).


●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 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.


●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 each channel can be switched, you can set whether to display


The maximum value, minimum value, and gas name can be viewed in the history graph.


●Automatically track the zero point to prevent drift, temperature compensation, multi-level calibration


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