Dual Analog Outputs

RH411
Unique Dual Display for Simultaneous Indication of BOTH Temperature and Relative Humidity
Dual Simultaneous Analog Outputs for Temperature and Relative Humidity
ºC/ºF Switchable
Display Hold
Min/Max Storage
Sleep Mode to Prolong Battery Life
Digital Calibration for Accuracy and Repeatability

The RH411 handheld digital thermo-hygrometer has a custom LCD display that lets you read temperature and relative humidity simultaneously. Perfect for any application where spot checks of temperature and relative humidity are needed, the RH411 offers fast and accurate measurements.

The combination temperature/humidity sensor connects to the unit through a 5' (1.5 m) cable. The sensor is housed in an easy-grip handle, in a protective metal mesh. Other unique features make the RH411 an even better value: digital calibration, display hold, min and max storage, and individual analog outputs for both temperature and % RH.
