WDL-18 Insulation Oil Volume Resistance Tester

WDL-18 typeInsulation oil volume resistivity testerDigital display of temperature resistivity, automatic control of aluminum bath temperature, automatic timing measurement of resistivity, and data locking. A new type of resistivity measuring instrument has been developed based on the principle of active bridge according to the power industry standard DL421-91 "Measurement of Volume Resistance of Insulation Oil". It has the advantages of simple structure, good linearity, high sensitivity, stable test results, and safe operation. Its performance is much higher than the usual voltage and current method. Used for measuring insulating oil Volume resistivity of fire-resistant oil and other media.

WDL-18 typeInsulation oil volume resistivity testerThe design is advanced, the structure is reasonable, the operation is simple, and it is safe and reliable. It is particularly practical for the application of oil quality supervision in the power sector. The test results comply with the provisions of the national standard DL421-91 "Insulation Oil Volume Resistance Measurement Method".
