The new compact class range from testo is suitable for installing and maintaining air conditioning and ventilation systems, servicing heating systems, ensuring indoor air quality and comfort, measuring pressure across HVAC and industrial applications, or measuring temperature in food and laboratory environments.

Smooth and energy-efficient operation of air conditioning and ventilation systems can only be ensured by regular measurements of the relevant parameters. With the new compact measuring instruments testo 417, testo 416, and testo 425, flow and volume flow measurement in ventilation ducts, at air inlets and outlets and when adjusting balanced residential ventilation is easier than ever, the company says.

Thanks to the new compact measuring instruments testo 535, testo 545, and testo 625, CO2, illuminance, temperature, and humidity are controlled quickly, easily and precisely, ensuring a healthy indoor climate that promotes performance.

The two new differential pressure measuring instruments, testo 512-1 and testo 512-2, can be used to measure low and high pressures quickly and precisely, when checking heating systems, for example. The all-new testo 512 manometers offer users a reliable tool for pressure measurement in industrial applications or for checking filters and Pitot tube measurement on air conditioning and ventilation systems, testo says.

With the new temperature measuring instruments testo 922, testo 925, and testo 110 (HACCP-compliant) and the large selection of probes (TE Type K, NTC, Pt100), even extremely high and low temperatures can be measured precisely, quickly, and easily in almost any medium. With the optional TopSafe, the instruments are protected against dust and water according to IP65.

The testo Smart App provides support for all measurements, with intuitive measurement menus for all HVAC applications, fast configuration, tabular and graphical display of measured values, second screen function, and uncomplicated documentation. The app can be downloaded free of charge from the Apple App Store and is regularly updated.
