Function Description of Ozone Toxic Gas Alarm:

Imported high-performance electrochemical sensors with excellent anti-interference performance and a service life of over 3 years
The instrument has functions such as 4-20mA/RS485 signal output (national standard Modbus signal output (RS485 interface), relay output, data recovery, data storage (optional), etc. It can be equipped with software, connected to a computer, automatically generates curve graphs, views historical data, and the storage time interval can be set by oneself
On site backlit large screen multi parameter LCD display, visually displaying gas concentration, type, unit, working status, etc
● Independent chamber, no need for on-site calibration when replacing sensors, automatic identification of sensor key numbers
● Full range temperature digital automatic tracking compensation to ensure measurement accuracy
● Full software calibration function, users can also calibrate by themselves, achieved with 4 buttons, simple operation, graphic dot matrix pure Chinese operation menu LCD interface.
● Level 2 alarm setting, dual relay signal output: one set of active DC24V output, one set of passive signal output
Can be equipped with an infrared remote control, no need to open the cover to set parameters in explosion-proof places, to prevent danger caused by static friction when rotating the cover. The instrument and infrared remote control can receive up to 8 meters, ensuring safe and reliable operation
