    Multi-function climate measuring instrument to monitor AQI

    Multi-function climate measuring instrument [VAC-435-1] is a versatile device which can measure several quantities that determine the quality of air like airflow, humidity, temperature, CO2 concentration, absolute pressure and so on with the help of appropriate high-quality probes. It also supports wireless probes when wires become a burden for any measurement application. It is powered by type AA batteries which are easily available. It has a large LCD display with backlight.


    1. It is used for measuring radiated heat.

    2. It is used to measure air and surface temperature.

    3. It is used to detect the presence of even small quantities of CO in ambient air with the help of the ambient CO probe.

    4. It is used for flow measurement in VAC ducts with the help of a pitot tube.

    5. It is used to measure air temperature and humidity in VAC grids.

    6. It is used to carry out flow measurements in ventilation ducts using thermal and vane anemometers.

    7. It is used to determine indoor air quality by measuring the concentration of CO2.

    8. It is used to measure volumetric airflow at the outlet of ducts.


    1. It is IP54 water-resistant certified.

    2. It is powered by type AA batteries which are easily replaceable.

    3. It supports a wide variety of high-quality sensors to be used with it for measuring temperature, CO2, humidity, etc.

    4. It has an illuminated LCD for using in low light conditions.

    5. The optional probes are specially designed to meet industrial requirements.

    6. It also supports wireless probes which is convenient and enhances safety.

    7. It allows measurements to be printed using the testo fast printer.

    8. It can display dew point.

    9. It supports an IAQ sensor air quality assessment by measuring parameters like CO2 concentration, temperature, humidity and absolute pressure to measure radiation heat.

    10. A lux sensor is connected to the instrument to measure illumination.


    1. Its display is made of LCD and is illuminated.

    2. It performs velocity measurements with hot wire anemometer at a resolution of 0.01 m/s in the range 0 to +20 m/s.

    3. The velocity measurement with vane anemometer is possible from 0 to +60 m/s.

    4. The resolutions of the vane anemometer are 0.1 m/s (16 mm vane) and 0.01 m/s (60 + 100 mm vane).

    5. The ambient COmeasurement range is from 0 to 10000 ppm with a resolution of 1 ppm CO2 using the IAQ probe.

    6. It is powered by AA batteries.

    7. It can last around 200 hours for typical vane measurements.

    8. It performs absolute pressure measurements within the range of 0 to 2000 hPa with an accuracy of ± 5 hPa and a resolution of 0.1 hPa.

    9. It is IP54 certified.

    10. It can be used with NTC, TC Type T (Cu-CuNi) and TC Type K(NiCr-Ni) probes for temperature measurements.

    11. The NTC probe has a measuring range of -50 to +150 °C with a resolution of 0.1 °C.

    12. The TC Type K probe has a measurement range of -200 to+1370 °C with a resolution of 0.1 °C and accuracy of ± (0.3 °C + 0.1 % of mv) and ± (0.2 °C + 0.5 % of mv) (remaining range).

    13. The TC Type T probe can measure in range of -200 to+400 °C with a resolution of 0.1 °C and accuracy of ± (0.3 °C + 0.1 % of mv) and ± (0.2 °C + 0.5 % of mv) (remaining range).

    14. Humidity measurement is done using a capacitive sensor which has a resolution of 0.1 %RH.

    15. It can measure humidity values from 0 to 100 %RH.

    16. It weighs 428 g.

    17. It has dimensions of 220 X 74 X 46 mm.
