Adopting imported high-performance electrochemical sensor, with good anti-interference performance, the service life of more than 3 years\
The instrument has: 4-20mA/RS485 signal output (GB standard Modbus signal output (RS485 interface), relay output, data recovery, data storage (optional) and other functions, can be equipped with software, connected with the computer, automatically generate graphs, view historical data, storage time interval can be set by themselves
On-site multi-parameter LCD display with backlit large screen, intuitive display of gas concentration, type, unit, working status, etc
Independent gas chamber, no need to replace the sensor calibration, sensor key number automatic recognition
Full range of temperature digital automatic tracking compensation, to ensure the accuracy of measurement
Full software calibration function, users can also self-calibration, with 4 buttons to achieve simple operation, graphics dot matrix pure Chinese operation menu LCD interface.
Two alarm setting, double relay signal output: one group of active DC24V output, one group of passive signal output
It can be equipped with infrared remote controller, no need to open the cover to set parameters in explosion-proof places, to prevent the danger caused by electrostatic friction when capping, the instrument and infrared remote control receiving up to 8 meters, safe and reliable operation
