Online dew point meter
Thread Content
Which manufacturers do you use for dew point meters used to measure the dew points of nitrogen and instrument air? Are their products stable? The portable models in our factory need to be calibrated frequently; we are considering using online dew point meters, so which manufacturer’s products are the best for that purpose?
Nitrogen: E+H dew point: VAISALA, GE
We use GE’s, and it’s quite stable!
Model from Xi’an Jueneng Instrument Co., Ltd.: JNYQ-D-20
Alumina sensor dew point meters are cheap
The first brand is GE PANA, which is relatively affordable; Vaisala/E+H/TELEDYNE
Our unit uses them in the instrument air pipelines; the manufacturer is VAISALA, model DMT142, and they still work well after being used
