Use the turbulence probe with the compatible testo 440 multifunction measuring instrument. Calculate the degree of turbulence and draft risk at the same time, in accordance with EN ISO 7730 / ASHRAE 55. The fixed cable is used to connect the turbulence probe to the 440 Air velocity and IAQ meter.

Use the CO probe with the compatible Testo 440 multifunction measuring instrument (sold separately) to detect carbon monoxide. The readings of the CO probe are transmitted to your measuring instrument with a connection cable. Store individual readings directly in the measuring instrument by pressing the button on the probe. The clearly structured measurement menus for long-term measurement enable the measuring instrument to be operated intuitively. Reading trends are reliably recorded thanks to the convenient input of measurement time and measuring cycle. You can use these trends to evaluate changes in the CO concentration.
