Ion current oxygen transmitter adopts imported ion flow sensor, which has the characteristics of no power supply, no consumption, long service life and easy maintenance. The transmitter comes with a standard RS485 communication port, which can realize two-way communication with the computer.
Ion current oxygen transmitter main features:
1. With display function, friendly man-machine dialogue menu, user operation is intuitive and convenient;
2. No reference gas is required, and is not affected by the working environment oxygen concentration;
3. The calibration interval is long, high precision, stable and reliable;
4. Any point calibration can meet the measurement accuracy of the whole range, and the operation is simple and quick;
5. Wall-mounted installation, easy to install and maintain.
