Testo 435-1 Multifunction HVAC Meter

The Testo 435-1 Multifunction HVAC Meter can measure a wide range of different HVAC-related parameters including air temperature, CO2 levels, humidity, absolute pressure, surface temperature, and air flow velocity. The range, resolution and accuracy depends on the type of probe attached and the meter is capable of taking two connections at once via two separate inputs. An optional radio module allows the connection of up to three wireless probes simultaneously. The meter is particularly useful for performing comprehensive assessment of indoor air quality.

Measurements and readings are displayed on the Testo 435-1’s large digital screen and operation is undertaken via the simple push button interface. Radio probes can operate at a distance of 20m and the meter features probe-dependent menus for individual measurement parameters as well as user profiles for both duct measurement and IAQ measurement. Calculation of dew point is a useful additional feature for IAQ assessment. The meter is capable of displaying min, max and mean values for each parameter.

The Testo 435-1 has rugged external housing which makes it ideal for use in challenging environments and it is compatible with the optional Testo fast printer. The printer can produce instant copies of single results or entire measurement sets, thus contributing to greater efficiency. The meter has a 200-hour battery life.
