The Sauermann Thermo-hygrometer Si-HH3 is a relative humidity & temperature measuring instrument.

In addition to the measurement of relative humidity & temperature, the dew-point, absolute humidity, enthalpy, mixing ratio and wet bulb temperature can be calculated.




General Features


*Battery life given at 20°C (68°F) with alkaline batteries.
**The sensor shows best performance when operated within recommended normal temperature and humidity range of 5°C–60 °C and 20 %RH –80 %RH,
respectively. Long-term exposure to conditions outside normal range, especially at high humidity, may temporarily offset the RH signal (e.g.+3%RH after 60h kept
at >80%RH). After returning into the normal temperature and humidity range the sensor will slowly comes back to calibration state by itself.
***If the instrument is stored outside the operating temperature (for example in a van, a warehouse, etc.), please wait for 10 minutes in its operating
temperature before starting and using it


Technical Specifications




1Drift : 0.25 %RH/year typical value for operation in normal T/RH (temperature and humidity range of 5°C to 60 °C and 20 %RH to 80 %RH respectively). Maximum
value is < 0.5%RH/yr. Higher drift values might occur due to contaminant environments with vaporized solvents, out-gassing tapes, adhesives, packaging materials
*All the accuracies indicated in this technical datasheet were stated in laboratory conditions, and can be guaranteed for measurements carried out in the same
conditions, or carried out with calibration compensation.
**Calculated values / ***Calculated values, only available on the app

Si-HVACR Measurement Mobile App





Si-HVACR mobile app makes measurements more user-friendly

Si-HVACR Measurement MobileApp delivers a user-friendly experience for the Si-TT3 / Si-TI3 / Si-HH3 / Si-VV3 / Si-PM3 Sauermann instruments.

This app displays on your smartphone screen all the results in real time and allows the management of measurement datasets over a duration of your choice, to create reports to be saved and exported in PDF, CSV or XML format.

  • Si-HVACR Measurement MobileApp relays the following measurements:
  • Temperature (thermocouple, NTC, ambient, infrared)
  • Relative humidity
  • Pressure
  • Air velocity
  • Calculated parameters (air velocity, airflow, dew point, absolute humidity, enthalpy, mixing ratio, wet bulb temperature).
