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).
