Description:The performance of the Guildline Model 8400 Laboratory Salinometer (Autosal) was evaluated in detail by the National Oceanographic Instrumentation Center of the National Ocean Survey of the National Oceanic and Atmospheric Administration. The salinometer is designed to offer high accuracy (±0.003 part per thousand) and employs a measurement principle entirely different from that of other available instruments. The investigation included testing for overall accuracy, repeatability, and stability of the conductivity ratio measurements as well as the effects of variations in bath temperature, ambient temperature, and power supply voltage and frequency. The performance of the instrument was found to exceed the published specifications of the manufacturer. Results are presented in detail, notably that the conductivity ratio accuracy was better than ±1 part per million equivalent salinity.
