Temperature/Humidity Meters & Sensors Temperature/Humidity 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.
