Palm-Sized Temperature/Humidity Meters

Palm-Sized Temperature/Humidity Meters

  • 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

The palm-sized series is reliable and accurate temperature/ humidity meter with a measuring humidity range of 0 to 100%RH by using a new developed humidity sensor that comes in three types, depending on application.


  • Environmental testing equipment
  • Chambers
  • Clean benches
  • Food storage, grain storage, greenhouses
  • Art galleries, museums
  • Food transport trucks
