- Commodity name: Dew Point Meter - Portable
DPM-16H
Function：
The meter uses the electrolytic method to measure the moisture content or dew point of non-corrosive gas or acid gas.
Principle:
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.
Standards：GBT 5832.1.
Characteristics：
- High precision, 10 ppb.
- Wide Test range, -80℃Td~-6 ℃Td.
- Corrosion resistance - It can measure acid gas and slightly corrosive gas.
- High-performance rechargeable battery - over 12 hours of continuous operation.
- Easy to use - direct measurement with gas connection, without bypass flushing.
- Sensor safety - with a sensor over range protection function.
