Ozone Gas Monitor Controller with Alarm

Short Description:

Model: G09-O3

Ozone and Temp.& RH monitoring
1xanalog output and 1xrelay outputs
Optional RS485 interface
3-color backlight display three scales of ozone gas
Can set the control mode and method
Zero point calibration and replaceable ozone sensor design

Real-time monitoring air ozone and optional temperature and humidity. Ozone measurements have temperature and humidity compensation algorithms.
It provides one relay output to control a ventilator or ozone generator. One 0-10V/4-20mA linear output and a RS485 to connect a PLC or other control system. Tri-color traffic LCD display for three ozone ranges. The buzzle alarm is available.
