Detailed introduction:

Product Introduction: TYDZ-02 insulation oil volume resistivity is applicable to DL 421-91 standard. This standard is suitable for measuring the volume resistivity of liquid media such as insulation oil and fire-resistant oil. Volume resistance is the ratio of the direct current voltage applied between the two poles in contact with the test solution to the current passing through the test solution. This instrument is designed with a dual cup structure, with one cup position capable of controlling temperature by 20 ℃ and the other cup position capable of raising temperature to 90 ℃. The human-machine interface uses LCD Chinese display, menu click input commands, automatic printing of test results, high measurement accuracy, stability and reliability.
