Abstract
An instrument for the measurement of temperature and chlorinity of water in situ is described. A thermistor is used for temperature measurement, and an electrical conductivity cell, the temperature coefficient of which is compensated by means of the thermistor, is used for chlorinity. The instrument is direct reading, with ranges of 0-30[degree]C for temperature and 0-16 ppt (parts per thousand) and 16-20 ppt for chlorinity. The accuracy is [plus or minus] 0.1[degree]C for temperature, and [plus or minus]0.05 ppt for chlorinity on the higher range. When used in the laboratory as a transfer instrument, an accuracy of [plus or minus] 0.02 ppt in chlorinity can be obtained.This publication has 6 references indexed in Scilit:
