HN-CH Series Palm-sized Temperature/Humidity Meters

The HN-CH series is reliable and accurate palm-sized temperature/ humidity meter with the measuring humidity range of 0 to 100%RH by using a new developed humidity sensor.
It also provides the data logging function capable to store each 8000 readings of temperature and humidity into memory.

Features

  • Excellent reproducibility and reliability by capacitance type humidity sensor
  • Humidity sensor with quick response in 15 seconds
  • Easy maintenance by complete interchangeable sensors
  • Handheld type, desktop type and wall-mounting type are available for various applications.
  • Data logging function capable to store each 8000 readings of temperature and humidity into memory
  • The sensor used in probe type and separated type can be used in temperature from -40 to 80°C.
  • With RS-232C or RS-485 communications interface
  • A software package for analyzing data is available.
  • Power supply of AA alkaline batteries or through AC adapter
