    Testo 435-2 Multifunction HVAC Meter

    The Testo 435-2 Multifunction HVAC Meter can work with a wide range of optional probes in order to measure parameters related to indoor air quality such as air temperature, humidity and CO2 concentration. These capabilities allow calculation of dew point and there is a specific user profile for assessment of IAQ. It is also possible to connect surface temperature probes, pressure probes, and air flow probes to the meter.

    Through additional optional probes, the Testo 435-2 is also capable of measuring light levels, U-value temperature, and turbulence. An optional radio module can be added to the HVAC meter so three probes can work with it simultaneously whilst there are physical inputs for two probes at once.

    The Testo 435-2 has a backlit digital display which can show multiple measurement parameters and calculations simultaneously. Minimum, maximum and timed mean readings can be shown on screen and the meter has an internal memory for 10,000 measurement values. Specific user profiles for individual parameters make the HVAC meter easy to use and it comes supplied with PC software for analysing, archiving and documenting readings. Hard copies can be produced directly from the meter with an optional Testo fast printer.

    A rugged casing made of ABS, TPE and metal gives the Testo 435-2 an IP54 ingress protection rating so it is ideally suited for use in challenging conditions. The meter benefits from a 200-hour battery life and has dimensions of 220mm x 74mm x 46mm.
