RH401: Digital Psychrometer + InfraRed Thermometer
Humidity, Wet bulb, Dew Point, Air Temperature plus Non-contact IR Temperature
The RH401 is a Digital Psychrometer with a Built-in IR thermometer that allows quick non-contact surface temperature measurements. Displays air temperature, humidity and surface temperature or dew point, humidity and surface temperature or wet bulb, humidity and surface temperature on a triple LCD with backlighting. The IR thermometer features adjustable emissivity and a spot/distance ratio of 8:1. The meter calculates the temperature difference between IR surface temperature and dew point. Ideal for spotting potential areas with mold. Other features include data hold, programmable auto power off and a retractable probe that protects the sensors when the meter is not in use. Includes hard case and four AAA batteries.
Features
- Triple display with backlighting
- Displays Air temp+RH+surface temp or Dew Point+RH+surface temp or Wet Bulb+RH+surface temp
- Built-in InfraRed Thermometer with laser pointer and 8:1 distance to target ratio
- Adjustable emissivity from 0.3 to 1.0
- Precision humidity capacitance sensor is retractable for protection during transportation and storage
- Calculates T1 (IR Surface Temperature) - DP (Dew Point) differential
