NHS-20
NHS-20 is also a high-performance and long life high polymer type humidity sensor. Since the impedance of NHS-20 is around one digit higher than NHS-12, it shows more accuracy in high humid area than NHS-12. Additionally, just simple measuring circuit is required because of its smaller temperature dependency and narrower distribution of resistance values as same as NHS-12. Appearance and dimensions are the quite same as NHS-12.

Humidity characteristics |
This sensor works with various flexible operational methods without strict restrictions, and has excellent resistivity to low humidity, high temperature/high humidity, and contamination by oil mists or cigarette smokes etc. The most suitable application would be for air conditioners, dehumidifiers, humidifiers, automatic dampers for green houses, etc.
This sensor shows high and constant accuracy from a lower range to higher range of humidity. In addition to the sensor it self, a ready-for-use measuring unit is also available.
A recommended measuring circuit is available upon request.
