EHO type intelligent micro water meterDetailed product description：

The EHO intelligent micro water meter adopts microcontroller technology, and the instrument realizes dew point PPmV、 Automatic conversion between units such as absolute humidity, without the need for manual table lookup conversion. The circuit part of the instrument is advanced and reliable. In order to meet the needs of field operations, the instrument adopts a dual-use of AC and DC, and the built-in battery can work continuously for more than 20 hours, which expands the range of use and greatly facilitates users.

Adopting the latest sensor technology from the world's advanced British ALPHA company, it utilizes DRYCAP thin film sensing technology and composite thin film humidity sensitive materials, and holds three world patents. The polyester film type probe DRYCAP is resistant to condensation, dust particles, and is not affected by gasoline and most gases.
The intelligent micro water meter adopts the principle of resistance capacitance method and uses a capacitive polymer film humidity sensor, which has the advantages of high accuracy, good repeatability, and small drift.
