2210009 ZD 21 Fixed Gas Transmitter with Internal Sensor, Oxygen (O2), 0 - 25% / vol. by GfG
A particularly long sensor life makes the ZD 21 a low cost transmitter for oxygen monitoring. The expected lifetime of the sensor is 5 years in continuous operation. A robust aluminum casing protects the sensor and the circuitry from impacts, splashed water, and dirt.
The ZD 21 is an "intelligent" transmitter. The comprehensive electronics allow for easy operation and maintenance and also increase operational safety and accuracy. In less than 2 seconds the ZD 21 responds to oxygen escaping from a leak. This extremely short response time allows the time to take measures to prevent considerable damage.
- Extremely stable oxygen (O2) sensor lasts 5 years
- Fast response
- No influences from pressure, humidity, or temperature
- No damage from carbon dioxide (CO2)
