testo 6612 - Process humidity probe for duct mounting

Image
The testo 6612 temperature and humidity probe is designed for measurements in air conditioning ducts.
  • IAQ probe for monitoring process temperatures and humidity
  • Measurement ranges: Temperature from -30 °C to +150 °C, humidity from 0 %RH to 100 %RH
  • Measuring accuracy of ± (1.0 + 0.007 * reading) %RH*
  • Easy installation with duct bracket and quick probe change thanks to digital interface and plug-in system
The probe is equipped with a high-precision, long-term stable humidity sensor from Testo and delivers precise measurement results. The duct bracket, the plug-in system and the digital interface all make installation, commissioning and probe replacement exceptionally quick and easy for you.

* Long-term stability: ≤ ±1% RH / year
1 x testo 6612 humidity and temperature probe, including factory certificate.
