| The limits of the additional relative error of the device when measuring optical quantities, due to a change in the sensitivity of the photometric head when the air temperature in the measurement zone changes by every 10 ° C in the range from -30 to 15 and over. +25 to 60 ° С | ± 3.0% |
The combined device “TKA-PKM” (63) implements the option of measuring the air velocity averaged over a certain period of time (100 s) (in accordance with the recommendations to SanPiN, see, for example, the Manual “Physical factors. Ecological and hygienic assessment and control “. M.” Medicine “, 1999, vol.2., P. 416).
