CTXL-TRH-W Portable/Wireless Universal Circular Chart Recorder

The CTXL–TRH recorder is designed for both local and remote monitoring of temperature and relative humidity. The standard sensor probe clips to the side of the unit, or may be detached and mounted up to 12 m (40′) away, using available extension cables. For even longer distances, the recorder is available with a wireless probe, which can be placed up to 90 m (300′) line of sight, or 33 m (110′) indoors away from the recorder. Simply plug-in the wireless receiver in place of the probe into the recorder, and you’re ready to go. The CTXL-TRH is available with specialty paper charts, with optimal ranges marked right on the chart, so you can easily see from a distance that the temperature and humidity readings are within range.
