HM1520LF Humidity Transducer

Brand: American Sensor Technologies Inc
Request Information Favorite
Based on the rugged HS1101LF capacitive humidity sensor, HM1520LF is a dedicated humidity transducer designed for measurements at low humidity.

Direct measurement of dew point or water concentration can be easily obtained in really cost effective conditions. Direct interface with a micro-controller is made possible with the module’s linear voltage output.
Features
  • Full interchangeability
  • Not affected by water immersion
  • Controlled temperature dependency
