Abstract

A simple digital spectral absorption meter for optical radiation from liquids designed for operation in the field is described. High measurement stability and linearity of the transfer characteristic were achieved through the use of a modification of the zero-measurement method. The maximum value of the nonlinearity of the transfer characteristic of the meter for the full measurement range did not exceed three to four low bits of the 10-digit digital code.
