The TRH-1000 temperature and relative humidity logger is a self-contained electronic device that records changes in temperature and relative humidity. When the logger is connected to a Windows®-based computer, readings can be viewed as raw data or as graphs. Weighing 2.6 ounces (74 grams), it can be mounted on walls or other surfaces and can be used in confined settings or for inconspicuous use, the company states. The datalogger has a temperature range of -40 degrees F to 158 degrees F (-40 degrees C to 70 degrees C) and is accurate to ±0.9 degrees F at 77 degrees F (±0.5 degrees C at 25 degrees C). The relative humidity accuracy is ±4 percent from 10 percent to 90 percent. The datalogger comes with software and an interface cable.
