The circuit resistance tester is mainly used to measure the contact resistance between conductive components in electrical equipment, especially the contact points in high current circuits. It is particularly suitable for measuring contact resistance in key parts such as power systems, high-voltage
Gas Chromatography (GC) is an analytical instrument widely used for separating and analyzing volatile and semi-volatile compounds in mixtures. Its primary applications include:Chemical AnalysisSeparation, identification, and quantification of components in complex mixtures.Used in environmental, pha
1. Testing (CT) current transformer: Open the machine and select the CT testing interface, choose the type of transformer such as M metering level, P level, etc; Check the options that need to be tested, such as excitation, transformation ratio, error, resistance, load, etc., and set the test parame
1. Connect the power supply, connect the current output terminal to the primary side of the tested current transformer, and connect K1 and K2 to the secondary side of the current transformer. Short circuit the normally closed switch, otherwise the test cannot be carried outPS: In practical applicat
Pour point and solidification point are important indicators used to describe the fluidity of liquids, especially oils, under low temperature conditions. They are all key parameters for measuring the low-temperature performance of oil products.1、 Pour a littleDefinition: Pour point refers to the lo
