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 humidity/temperature probe head.

Proven quality from Testo: you can depend on reliable measurement results, because the probe head is equipped with our long-term stable humidity sensor. This is traceable to international humidity standards, such as ILAC, PTB and NIST.

• Intuitive: parallel determination of relative humidity and air temperature in indoor areas, including long-term measurement

• Precise: measuring accuracy ±2% RH / ±0.5 °C, measuring range: 0 to 100% RH / -20 to +70 °C

• Convenient: probe head is easy to attach to the universal handle with Bluetooth® or cable (available to order separately)

• Intelligent calibration concept: only send in the probe head for calibration
