ZD21 Series Fixed Transmitters - Long-term monitoring of oxygen concentrations in difficult conditions, by GfG Instrumentation
ZD21 Transmitter - Monitor O2 in difficult conditions. In many areas of application, oxygen concentrations must be monitored consistently. If harsh environmental conditions such as varying temperatures, high or low pressure or dry or humid air necessitate a particularly durable transmitter, the ZD21 is a good choice. The sensor operates with a zirconium dioxide oxygen pump cell. This measuring principle enables stable long-term measurement of O2 in difficult conditions and with short response times.
