The multifunction indoor air quality meter allows you to carry out a variety of different measurements to inspect and adjust ventilation and A/C systems and carry out indoor air quality testing. Also comes with an integrated pressure difference sensor for measurements with pitot static tube and filter monitoring.
The extremely versatile Testo 435-4 can measure a host of variables including air temperature, air flow, volumetric flow rate, humidity and lux. And because you know best what your multifunction meter needs to be able to do, you can configure it using any one of the many optional sensors and probes. You can also connect up to 3 wireless sensors whose measurements can be picked up by a wireless module (optional) over a distance of up to 65 feet. This allows you to carry out quick and easy measurements at places which would otherwise be extremely difficult to reach. There's also a special optional carry case that can hold both your meter and the probes and sensors that make up your individual set.
