Testo 435-1 IAQ Kit - Temp, Humidity, Co2 & Absolute Pressure

The Testo 435-1 IAQ Kit is a multifunction instrument for measuring and assessing Indoor Air Quality and for adjusting and inspecting VAC systems.The Testo 435-1 is an affordable introduction to measurement engineering for ambient air conditions. Readings from up to 3 temperature probes can be displayed on the screen. Measurement data can also be printed on site with the Testo printer.

The Testo 435-1 IAQ Kit measures the following parameters

  • Relative humidity
  • Temperature
  • CO2
  • Absolute Pressure

The Testo 435-1 indoor air quality meter allows you to carry out a variety of different measurements which enable you to inspect and adjust ventilation and air conditioning systems and carry out indoor air quality testing.  In addition to the many other functions and features which its smaller brother, the 435-2, has, the testo 435-4 also has an integrated pressure difference sensor for measurements with pitot static tube and filter monitoring.

Complex technology, but really easy handling

The Testo 435-1 multi-function climate measuring instrument is characterized by an efficient measuring process which makes any inconvenient programming of the measuring instrument superfluous:

probe-dependent menus and selectable user profiles for the typical applications of “IAQ measurement” ensures the easy handling.

All readings are easy to read on the large display which has an illumination function. In addition, dew point distance, min., max. and mean values are displayed. A solid housing provides reliable protection against impacts for the Testo 435-1 multi-function climate measuring instrument.

Documentation of measurement data on site

The Testo fast printer, which is available as an option, means you can create a report printout of measurement data directly on site. For a duct measurement, you can for instance print out the current readings or the min./max. values for air velocity, volumetric flow, temperature and air humidity. You can use the printout as evidence of your work.

Use the practical cyclical printing function on the testo 435-1 as well. It not only enables the printout of individual readings, but also of whole series of measurements on the Testo fast printer at freely adjustable intervals (for example once a minute).

THIS PRODUCT INCLUDES AN IAQ PROBE, A ADDITIONAL RANGE OF PROBES CAN BE FOUND IN ACCESSORIES
