The HT82 Air Oxygen Gas Transmitter is used to measure the oxygen concentration of the air and has an LCD display to display the gas concentration and perform the settings of the device and also has the serial port MODBUS / RTU-RS485. This device can be ordered in a variety of oxygen gas concentration ranges. The oxygen sensor can be produced internally or by probe. Optionally, an output channel of 0 to 10 volts (0to10V) and an output channel of 4 to 20 mA (4to20mA) and two output relays are placed on the device. Each analog output channel operates independently and can be set to different values. Analog output values can be adjusted by the software.
Oxygen sensor
1) Range 0 to 25%
2) Range 0 to 100%
* The sensors are of electrochemical type and their lifespan in air is 2 years. The measurement accuracy of the sensors is less than 2% of the read value.
