O4 Single Gas Detectors | Portable Gas Detector Sensor | CO-04 (C-)
The 04 model is a portable single gas detector that boasts a robust design with new advanced R sensors that deliver accurate readings.
With a continuous operating time of approximately 9,000 hours, the new O4 series is designed to function long-term under hazardous conditions. The sensors’ durability and performance are backed by a three-year warranty* (one-year sensor warranty for OX-04G).
Besides O2 gas detection, the 04 series also offers CO sensors that are almost entirely resistant to hydrogen interference. This makes it ideal for use in environments like steel facilities where hydrogen is present.
