Water Vapour Transmitter
Novatech has enhanced its range of analysers by adding the 1735 Water Vapour Humidity Transmitter and the 1231HWV oxygen probe. The 1735 transmitter uses the measure of oxygen to calculate the level of water vapour by using the difference between the wet oxygen reading and the dry oxygen reading.
The Novatech zirconia probes incorporate the world’s most rugged zirconia sensors. Now there is a Novatech oxygen probe designed especially for cooking, baking and roasting ovens.
Used with the 1735 water vapour transmitter, the 1231HWV oxygen probe is capable of reading the oxygen concentration in atmospheres with up to 99.99% water vapour and at temperatures up to 600°C.
The state of the art analyser provides analogue- and digital outputs to feed your process control computer.
Keyboard set in any of the following ranges:
- 0 to 100% water vapour
- 0 to 100°C dew point
- 0.0 to 10.0 g/m3 absolute humidity
- 0.00 to 1.00 kg/kg Mass fraction
- 0 to 100% dryer RH
- 0 to 25% oxygen
All ranges have an adjustable zero and span.
Two isolated 4-20mA or 0-20mA DC linear outputs for
