400563 4355 435-4 IAQ Kit with Memory by Testo

The ambient air conditions measuring instrument, for asssessing Indoor Air Quality and tuning and testing VAC systems, stands out on account of its efficient measurement process. The user-friendly measuring instrument has the right measurement engineering for every application and different flow speeds; for example, thermal probes, vane or Pitot tube measurement. Probe-controlled menus and selectable user profiles, e.g. for duct measurement or long-term measurement, ensure the user-friendliest operation possible. The new IAQ probe measures Indoor Air Quality by measuring the CO2 level, air moisture and air temperature. In addition, lux and comfort level probes can be connected to measure draught air. Clear analysis and archiving ensure convenient documentation. Temperature and humidity measurement is built-in in the new thermal probe. The special flow protocol professionally documents duct measurements. It is also possible to connect additional temperature and humidity probes. Readings from up to 3 temperature or humidity probes can be displayed in the measuring instrument; data transmission is by radio, i.e. wireless.

8721 0025 Flow Matrix by Testo

The air flow grid (in conjunction with the appropriate measuring instrument) is your ideal measurement solution for determining flow velocity and volume flow on laminar flow supply air diffusers.

Use the air flow grid to carry out accurate measurements on laminar flow supply air outlets. Use in conjunction with a differential pressure measuring instrument (e.g. testo 420, testo 480 or testo 435-4) to calculate flow velocity and volume flow.

The air flow grid (360 x 360 mm) can be used over a large area and is particularly suitable for carrying out measurements on HEPA filters and safety cabinets in cleanrooms.

Particularly useful: you can also use the screw-on telescope (can be extended to 1800 mm) to carry out volume flow measurements on high ceiling diffusers.

• Volume flow measurement on large supply air diffusers, HEPA filters and safety cabinets in cleanrooms
• The telescope makes it possible to carry out measurements on high ceiling diffusers
• Ideal for large surface areas
• Air flow grid dimensions: 360 x 360 mm
