Plug-in humidity / temperature probe

Order-Nr.  0572 2154

  • Measures air temperature and humidity quickly and reliably

  • Compactly connected to the logger: the probe is plugged directly into the logger

  • Intelligent calibration concept

  • Measurement range: humidity 0 to 100% relative humidity; temperature -30 to +50 °C

Measure relative humidity and temperature extremely precisely: with the plug-in, digital humidity and temperature probe (Ø 12 mm).


Product Description

The plug-in humidity/temperature probe is suitable for measuring temperature and relative humidity in storerooms, cold storage areas and work rooms or in air conditioning/ventilation ducts.

The humidity/temperature probe is plugged directly in and is therefore compactly connected to the instrument/data logger.

The applications at a glance

Use the high-precision humidity and temperature probe (with an appropriate measuring instrument) for the following applications:
  • Measuring the relative humidity and temperature in storage, refrigerated and work areas or in air conditioning/ventilation ducts
  • Assessing thermal comfort
  • Checking the correct ambient conditions in production facilities to comply with quality standards

Always reliable measurement results

Thanks to the good air flow, the humidity sensor for measuring relative humidity has a considerably faster response time in comparison to a humidity sensor installed in a housing. Thanks to its long-term stability, you can still count on measurement results that are reliable and correct, even after years of use.

Intelligent calibration concept

The humidity/temperature probe offers the highest digital measurement certainty. The digital probe allows readings to be processed directly in the probe. This technology eliminates instrument measurement uncertainty. The probe can be sent in for calibration on its own (without the data logger).
