If the testo 350 is not used for measurements over an
extended period, but rather, for example, for random
measurements during start-up, servicing and adjustment of
industrial combustion systems, process systems, power
plants, gas turbines or stationary industrial motors, an
annual check of the testo 350 by testo service is
recommended.
