RS232 Communication

Environment temperature: -10~+50°C Environment Humidity:<80%RH

Sample gas pressure: atmospheric conditions±10% (Gas outlet should be atmospheric conditions)

Storage environment: -10~+50°C,environmental humidity less than 90%RH,no condensed water.When the storage and transportation environment temperature is lower than 5°C,the transmitter should be placed in the normal working temperature environment for more than 4 hours before use.
