TRH300 Temperature, RH & Light Module for the XR440 Pocket Logger. The TRH-300 module converts the 4 input channels as follows: Channel 1: Temperature, Range -40 to +60°C; Channels 2: Light, Range 0-15,000 foot candles; Channel 3: Relative Humidity, Dew Point or Wet Bulb Temperature readings, Range 0-90%RH; Channel 4: Standard Input (0-5vDC, Pace Sensors or resistive inputs). Module adds 9mm to overall length of an XR440.

Miniature module plugs into XR440 Data Logger, replacing its detachable terminal block. Uses three channels, one for temperature, one for relative humidity (Relative Humidity may be read and displayed as Dew Point or Wet Bulb temperature) and one for Light. Same accuracy specifications as the TRH-100 Temperature and Relative Humidity Probe. Maximum operating temperature is 60°C (140°F) vs 85°C (185°F) for the TRH-100 Probe, and RH range is 0-90% vs 0-95% for the TRH-100 Probe. One spare channel is available on the module for connecting to other Pace sensors, or reading a resistance or a dc voltage.
The module’s Light Sensor is similar to the LS-100 Light Sensor.
Operating Temp: -30 to 60°C (-22 to 140°F)
Humidity Range: 0-90% RH.
Light Range: 0-15,000 Foot Candles
Size: (41mm Wide x 19mm Deep x 19mm High. Adds 9mm to XR440’s overall length.
One foot candle is based on the amount of illumination provided by 1 candle at a distance of 1 foot (Equivalent to one lumen per square foot, or 10.764 Lux)
