CO probe, fixed cable

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.• Intuitive: clearly structured measurement menus for multiple applications• Precise: calculations are performed automatically inside the Testo 440 application screens• Convenient: Universal connection handle can be easily combined with other probe heads• Intelligent calibration concept. Only the probe tip needs to be sent for calibration.
