Wide Area Oxygen Transmitter (CI-PC986)
-
Meets measurement accuracy requirements across a wide range of 1 ppm to 25%.
-
The transmitter features voltage regulation and automatic flow control, making it suitable for positive pressure applications.
-
Uses a digital sensor that allows on-site replacement without requiring recalibration.
-
Includes an overvoltage (pressure) protection function: when pressure in the test chamber exceeds the preset range, the system automatically shuts off the gas path to prevent sensor damage caused by excessive or insufficient pressure.
