- Commodity name: Online Dew Point Meter
Perform on-line measurement of the dew point of non-corrosive gas and acid gas, or trace water content in the gas.
The coil-like double platinum wire and its gap (less than 20um) constitute an electrolytic cell. Phosphorus pentoxide in the gap between platinum wires absorbs trace water to produce phosphoric acid and generates a weak current. The current is proportional to the amount of water absorbed. The dew point or trace water content is calculated according to the measured current.
High precision, 10 ppb.
Wide Test range, -80℃Td~-6 ℃Td.
Corrosion resistance - It can measure acid gas and slightly corrosive gas.
The gasification chamber is used to heat the liquefied gas.
Sensor safety - with a sensor over range protection function.
Meter net - more than 100 meters can be monitored by a computer.
Explosion-proof class, ExdIIBT4.
With constant temperature function, it can be used stably under various climate conditions.
