For this reason, the measuring instrument should only be switched on in an atmosphere free of CO. Values will be too low otherwise in subsequent measurements.

Page 30: Co/Co Measurement
(testo 445) The 0632.1240 probe measures concentrations from 0 to 1 vol % CO 2 . The unit can be switched between ppm and vol% as described in “Parameter settings” on page 16. The measuring principle is based on infrared absorption. The probe has a relatively high power consumption on account of its sensor. -
