Hot Wire Probe Head including Temperature and Humidity Sensor

Brand: Testo

More applications, less equipment: if you already own one of our probes with a universal handle, you can easily expand your portfolio of probes with the hot wire probe head.

Simply plug the probe head onto the extendable telescope for air velocity probes and use the adapter (order number 0554 2160) to attach them both to the handle with Bluetooth or cable.
Features
  • Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement
  • Precise: includes absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity
  • Convenient: simply plug the probe head onto the extendable telescope for air velocity probes – and use the adapter to attach them to the universal handle with Bluetooth® or cable (available to order separately)
  • Intelligent calibration concept: only send in the probe head for calibration
