1732 Dual Probe Oxygen Transmitter

1732 Dual Probe Oxygen Transmitter

Optimum Combustion Reduces your Fuel Bill

This helps the whole world and future generations by reducing harmful greenhouse gas emissions. The current high cost of fuel has helped to reduce the payback period for the cost of installing oxygen monitoring and air / fuel ratio control. It makes sense to consider the benefits of installing an oxygen system on your combustion process.

If your particular process is not listed above then we would love to hear from you. There is a good chance that Novatech Controls has an appropriate product for your process.

This is the sixth generation of zirconia oxygen transmitters designed and manufactured by Novatech Controls since 1980. This oxygen measurement is based on the world’s strongest zirconia sensor that was developed by the CSIRO’s Department of Materials Science.
Novatech Controls holds the exclusive rights to manufacture this unique sensor.

This sensor, combined with the state-of-the-art 1732 transmitter, provides the perfect solution for your gaseous oxygen measurement.
