Connect the manometer at the pressure element and enter the coefficient. You can also connect a Pitot tube and enter the coefficient and duct dimensions. | | [![](https://sauermanngroup.com/sites/default/files/img/TT3.png)Si-TT3](https://sauermanngroup.com/en-GB/measuring-instruments/portable-instruments/thermometers/si-tt3) Dual input thermocouple thermometer | **Water heaters** | **Multifunction** | **Refrigerators, freezers** | | - Compare the water temperature in the boiler outlet and return pipes. | \- Ambient air temperature \- Air temperature in the ducts \- Temperature in domestic hot water systems | - Measure superheat and sub-cooling of the refrigerant gas circuit. | | **Tip:** The smartphone app records the temperatures, and delta temperatures, over time to see that installation is working correctly. Can be viewed as a table or a graph. | | [![](https://sauermanngroup.com/sites/default/files/img/TI3.png)Si-TI3](https://sauermanngroup.com/en-GB/measuring-instruments/portable-instruments/thermometers/si-ti3) Infrared thermometer | **Radiators** | | | - Measure radiator hot and cold spots to determine if venting is required. | | **Tip:** Vastly improves speed and convenience (measurements delivered remotely in real time). Can measure ambient temperature (via app). Quickly see if you have overheating sources, for example on an electric installation. Affix a black strip on non-black surfaces. Adjust the emissivity of the surface (as per the manual) from 0.10 to 1.00 for accurate measurement. | | [![](https://sauermanngroup.com/sites/default/files/img/HH3.png)Si-HH3](https://sauermanngroup.com/en-GB/measuring-instruments/portable-instruments/hygrometers/si-hh3) Thermo-hygrometer | | **Ventilation** | | | - Measure ambient air temperature and relative humidity. | | **Tip:** Extreme relative humidity values (too high or too low) can pose hazards (allergies, germs, dust, mould, etc.). The app shows psychrometric parameters, such as dew point and wet temperature. | | [![](https://sauermanngroup.com/sites/default/files/img/VV3.png)Si-VV3](https://sauermanngroup.com/en-GB/measuring-instruments/portable-instruments/thermo-anemometers/si-vv3) Vane thermo-anemometer | | **Air-conditioning circuit** | | | Measure air flow through system inlet and outlet air vents. | | **Tip:** Input the duct cross-section in the app to calculate average air flow rate in addition to air velocity. | ![](/sites/default/files/styles/webp/public/images/icon-lcd.png.webp?itok=OHVSeK-6) Backlit LCD screen .centered-title{text-align:center;font-weight:bold;} ![](/sites/default/files/styles/webp/public/images/icon-battery.png.webp?itok=-IW7emhS) Long-battery life ![](/sites/default/files/styles/webp/public/images/icon-magnet.png.webp?itok=MrBSZ9l6) Magnetic backing for easy fixing ![](/sites/default/files/styles/webp/public/images/icon-bag.png.webp?itok=3CDbnZ6d) Carrying bag ![](/sites/default/files/styles/webp/public/images/icon-phone.png.webp?itok=KeQMnQJb) Calculated values on mobile App ![](/sites/default/files/styles/webp/public/images/icon-report.png.webp?itok=ebrDZb0i) Reports creation on mobile App Si-HVACR Measurement mobile App **Mobile App** The Sauermann Si-HVACR Measurement MobileApp allows to view and record measurements in real-time. - Easily view different parameters - Browse saved measurements history and data graphs (average, min & max values, etc.) - Create reports (PDF, CSV or XML format) and add up to four (4) photos ![](/sites/default/files/styles/max_1300x1300/public/images/app_1.png?itok=7tLBUL9l) .separator::before{ content: ''; background: url(/themes/custom/entityone/src/images/shadow-divider.png) no-repeat center center; display: block; position: absolute; top: -20px; height: 40px; width: 100%; } ### Leak detection | | ![](https://sauermanngroup.com/sites/default/files/img/combustion.png)Heating | ![](https://sauermanngroup.com/sites/default/files/img/ventilation.png)Ventilation | ![](https://sauermanngroup.com/sites/default/files/img/climatisation.png)Climatisation | ![](https://sauermanngroup.com/sites/default/files/img/refrigeration.png)Refrigeration | |---|---|---|---|---| | [![](https://sauermanngroup.com/sites/default/files/img/CD3.png)Si-CD3](https://sauermanngroup.com/en-GB/measuring-instruments/portable-instruments/gas-detectors/si-cd3) Gas leak detector | **Gas-fired boilers** | | | Detects leaks of combustible gases upstream of the boiler, at the inlet and inside the unit. | | **Tip:** A flexible probe keeps the device’s sensor in contact with gas pipes in even the hardest-to-reach places.
