Sauermann Si-PM3 - Digital Differential Pressure Manometer

Technical Specifications

Air velocity displayed on the instrument is calculated at fixed conditions: L Pitot tube with a deprimogen coefficient of 1.0015, at 20°C
(68°F) and 1013.25 hPa (29.92 inHg). When the app is used to display air velocity, these parameters can be modified.

*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, only available on the app / ***Calculated values

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).
