The production of CHANG AI complies with the requirements of ISO quality certification.
CI-PC18 Series hygrometer Product Features
Simultaneously monitor the humidity and oxygen concentration in the sample gas;
The split structure design is adopted, and the probes are all made of high-temperature-resistant materials, so that the probes can be used in high-temperature and high-humidity environments;
User-specific communication codes, transmitters obtained from other sources cannot be docked;
Use RS485/RS232 two-way communication;
Simple structure, easy installation and maintenance.
