RH820 Handheld Humidity Temperature Dew Point Meters 09431

 High performance humidity handheld meters available with USB or wireless connectivity. They offer a double display to show the temperature and humidity from built in sensors and can alternately display data from a separate Type K thermocouple connected via SMP type miniature connector. Save function allows storage of up to 256 readings (no time-stamp) to internal non-volatile memory. Software for USB and wireless versions is included to allow internal, external temperature, and RH data to be recorded by a PC. Interface cable is included with the USB version; receiver with the wireless version.

• USB Port Provides Excellent User Interface (RH820U)
• Wireless 2-Way Transmission (RH820W)
• 2 Temperature Sensors (Internal NTC and External K-Type) and Humidity Sensor Together
• Wet/Dry Bulb, Dew Point and %RH
