Industrial HN-P30 Humidity Sensor

Industrial HN-P30 Humidity Sensor is a legacy CHINO Corporation humidity sensing module designed for industrial environments. The HN-P30 is part of CHINO’s HN-P family of humidity sensors and is documented in CHINO's discontinued products lists, with production ceasing around August 2000. Historically marketed as an electronic hygrometer, the HN-P30 served as the humidity sensing element that could be integrated with CHINO measurement electronics for process monitoring and environmental control in manufacturing settings. In CHINO’s current technical materials, humidity sensors are often paired with dedicated humidity computation modules to deliver derived values such as relative humidity, dew point, and water vapor pressure; for example, combining a CHINO humidity sensor with a module like the HN-GVFA1 enables those calculations. For legacy equipment using the HN-P30, verify compatibility with existing CHINO controllers or service channels before attempting replacement or retrofit. This model illustrates CHINO's historical approach to industrial humidity sensing and how modern CHINO systems build on that foundation to provide precise environmental monitoring.
