Testo 435-1 Hotwire, Rotary Vane Anemometer, 40m/s Max, Measures Humidity, Temperature

Testo 435-1 Multi-Function Meter

From Testo, the 435-1 Multi-function meter designed for measuring adjusting and testing HVAC systems and assessing air quality. The professional hand-held meter provides instant, accurate readings allowing the user to easily pinpoint and troubleshoot areas of concern. Configurable with an array of different probes, the Testo 435-1 is the essential instrument for service engineers HAVC technicians and building inspectors

Ergonomically designed, the robust hand-held digital meter utilises a range of optional plug-in probes to deliver readings with a high degree of accuracy. Depending on the probe selected, the Testo 435-1 meter has the capability to measure temperature, humidity, CO2 and absolute pressure, air velocity and volumetric flow rates.

With an easy to navigate keypad and soft control buttons, operation of the Testo 435 is incredibly easy. Probe dependant menus and selectable user profiles for typical applications and measurements make complicated programming unnecessary. With minimal effort, the user can easily select the parameters and functions to be measured. With a large backlit LCD display, all collected readings are clearly shown on the front screen, even in low light conditions. A handy auto-off feature also helps to conserve battery life.
