Estimation of Standard Determinations of the Results of Vimiryuvan Different by Additional Electronic Colorimeter

The systematic errors that arise mainly due to the design flaws of measuring instruments, their improper installation, inaccurate calibration of scales and limbs, etc. are estimated. Systematic errors also arise when changing the parameters of the environment in which measurements are carried out. For example, when the temperature, pressure and humidity of the air. The influence of systematic errors on the measurement results should be identified in the process of work and taken into account when processing the measurement results. As an example, an estimate of the uncertainty of three the colors measurement channels by a colorimeter is presented.
