NHS-25
NHS-25 is also a high-performance and long life high polymer type humidity sensor. The impedance and humidity characteristics are the same as NHS-20, but NHS-25 is more resistive to dew condensation than NHS-20 because the surface of polymer membrane is treated to be hydrophobic. Then, this sensor keeps the excellent performances even if experienced repeated dew condensations. Additionally, just a simple measuring circuit is required because of its smaller temperature dependence and also narrower distribution of resistance values as same as NHS-12 and NHS-20. Appearance and dimensions are same as NHS-20.

Humidity characteristics |
This sensor can be operated with a wide operational condition range, and has excellent durability to low humidity, high temperature and high humidity, and contamination by such as oil mists or cigarette smoke. Adequate application would be for air conditioners, dehumidifiers, humidifiers, automatic dampers for green house, etc. A recommended measuring circuit is available on request. This sensor can be used for dehumidifiers and room drying apparatus. Modules for exclusive applications will be available upon request.
