Abstract
Photometer has connected optically monochromatic lamp, measuring channel equipped with sample holder (cuvette with liquid being controlled), photo-transformer and s auxiliary device. To the photometer former of calibration signal is included, and control block. The measuring channel is equipped with integrator, comparator and switchboard, at that the input of integrator is through switchboard connected to the input of the amplifier. The output of the integrator is connected to the first input of the comparator, to the second input of comparator output of the calibration signal former is connected. One output of the control block is connected to the input of the switchboard, and the other one – to integrator. The output of the comparator is connected to the auxiliary device.
