The testo 435-2 indoor air quality meter allows you to carry out all the measurements that are necessary to check and adjust ventilation and air conditioning systems and assess the indoor air quality. The IAQ meter also offers a wide range of probes and sensors to equip you to measure various parameters.

Product Description
The testo 435-2 indoor air quality meter is designed to allow you to carry out all the measurements that are necessary to check and adjust ventilation and air conditioning systems and assess the indoor air quality.

A wide selection of optional probes and sensors with the IAQ meter gives you the freedom to configure your meter just the way you want it. Order your probes and sensors along with your meter now.

Connectable sensors (optional) for Indoor Air Quality testing
- IAQ sensor for assessing the indoor air quality using CO2, air temperature, relative humidity and absolute pressure measurements
- Comfort sensor for degree of turbulence measurements in compliance with EN 13779 for the objective assessment of the air velocity in the relevant room
- Globe thermometer for measuring radiation heat
- Lux sensor for measuring illumination
- Moisture/temperature sensor for assessing the thermal comfort in the relevant room
- CO environmental sensor for measuring CO in rooms and buildings
- Temperature sensor for immersion, penetration, air and surface measurements
- Temperature sensors to determine the HTC value

Connectable sensors (optional) for checking and adjusting ventilation and air conditioning systems
- Thermal anemometer, also with integrated temperature and relative humidity measurement function for air velocity and volume flow rate measurements in ventilation ducts
- Impeller anemometer with small diameter(Ø 16mm) for air flow and volume flow rate measurements in ventilation ducts
- Impeller anemometer with large diameter (Ø 100mm) for air flow and volume flow rate measurements at air outlets in connection with the testovent 417 funnels also for carrying out measurements at disk valves and ventilation grilles or for carrying out measurements at ceiling diffusers using a volume flow rate rectifier
- Temperature sensor for immersion, penetration, air and surface measurements
- Moisture/temperature sensor for carrying out measurements in ventilation ducts
- Absolute pressure sensor

In addition to the other connectable sensors, you can also connect as many as three wireless sensors to your testo 435-2 IAQ meter: the optionally available wireless module allows you to carry out wireless temperature and moisture measurements via wireless sensors across distances of up to 20 meters out in the open. This helps to ensure that the cable is not damaged and that nothing gets in your way while measuring.

There is also a separate carry case available that provides you with plenty of room for both your meter and your selection of probes and sensors.

Complex technology that could hardly be more simple
The beauty behind testo 435-2 indoor air quality meter is that the whole measuring process can be carried out quickly and efficiently without any complex programming. Sensor dependent menus and selectable user profiles for typical applications like “duct measurements” and “IAQ measurements” ensure that the meter is always ready to use.

The testo 435-2 has a super-size memory that can save up to 10,000 measurements, which can be transferred to your laptop or PC via the included USB cable. The included software allows you to log, archive and clearly structure all relevant measuring data and measuring programmes, for example duct measurements. Specially adapted measurement protocols can be used to present your customers with data from duct, long-term and degree of turbulence measurements. The optionally available testo fast printer can be used toprovide your customers withon-the-spot protocol print outs.

The testo 453-2 has a large, easy-to-read backlit display that shows the dew point difference along with other values including min, max and mean values. A durable protective cover protects the testo 435-2 indoor air quality meter reliably against impact.
