GasTransmitter - Fixed Gas Detection System

ZD 21 Transmitter

Low cost long-term solution

Particular long sensor life makes the ZD21 a low cost transmitter for oxygen monitoring. The expected lifetime for the sensor is 5 years in continuous operation. A robust aluminium casing protects the sensor and the circuitry from impacts, splash water and dirt. 
The ZD21 is an "intelligent" transmitter. The comprehensive electronic allows for easy operation and maintenance and also increases the operational safety and accuracy. In less than 2 seconds the ZD21 responds to changing oxygen levels. This extremely short response time allows to take measures in time to prevent considerable damage.

• Expected lifetime: 5 years
• Extremely fast response time: t90< 2 sec.
• No influences from pressure, humidity or temperature
• No damage from CO2
• Maintenance free, service check every year
• Different detection ranges available
