This standard specifies the technical requirements, test methods, inspection rules, signs, Encasement, transportation and storage requirements of the electrolysis solid moisture measurement instrument. The instrument is used for the measurement of moisture content in solid samples. It is suitable for solid samples that can release moisture under normal temperature or heating conditions, but not for those samples that will destroy the five oxidation diphosphorus coating or electrode under measurement conditions. The standard details the normal working conditions of the instrument, including environment temperature 5 ℃~ 35 ℃, relative humidity ≤ 80%, power supply requirements and Miscellaneous environment requirements. Appearance requirements of the instrument also include uniform color and no obvious damage, etc., to ensure the use effect and life of the instrument.
