OVERVIEW
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.
Please note: NATA Calibration available – please call for pricing

Altitude: from 0 to 2000m (6561′)Storage Temperature From -20 to +70°C (-4 to 158°F)*** Auto Shut-off 10 minutes (can be deactivated) Weight (with batteries) 200g (7oz) *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 itTechnical Specifications

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).
