Dshd 421 Insulating Oils Volumetric Resistivity Tester - China

DSHD- 421 Insulating Oils Volumetric Resistivity Tester is a new

instrument specially developed for resistivity determination using the

active bridge principle as per the Industry Standard of People’s

Republic of China DL/ T421- 91 “Test Method for Volume Resistivity of

Insulating Oils”.

Equipped with parameters measurement system and oil

cup heating control system

DSHD- 421 Insulating Oils Volumetric Resistivity Tester can time, read readings and save test data automatically.

So as to achieve the advantages of simple structure, excellent linearity, high sensitivity, stability and safety.

Compared with the instrument using voltage or current method, the better it is.

Excepting to determine the volume resistivity of insulating oils, DSHD- 421 Insulating Oils Volumetric Resistivity Tester can also used to determine resistivity of transformer oil and lubricating oils.

Further more, DSHD- 421 Insulating Oils Volumetric Resistivity Tester is the best choice to determine volume resistivity of lubricating oils in the power industry, petroleum industry, scientific research institutes, and relative factories and companies.
