Dry-wet oxygen principle flue gas humidity transmitter has a high-precision temperature automatic compensation system that eliminates the effects of ambient temperature. It is with simple operation, long serving life and easy to maintain for features, etc.
Dry-wet oxygen principle flue gas humidity transmitter main features:
1.The auto-compensation system for temperature with high accuracy could eliminate the influence from environment temperature;
2.The function of pressure compensation with high accuracy could make the humidity measurement more accurate;
3.The upper and lower limits of the humidity referred to 4-20mA、0-10V output can be set freely to help users getting the analog output with higher accuracy;
4.The integrative design with built-in PID heat tracing function is easy to install and operate, and it can improve the analyzer's serving life and stability.
