Automatic PH Acidity Meter( Base of transformer oil and lubricating oil)

Purpose

The instrument is suitable to determine acid number of transformer oil and turbine oil. It is designed and made as per the National Standard GB/T264-83 "Test Methods for Acid Number of Petroleum Products". It takes a blue LCD for display. It can make determination, print test data automatically using a microprocessor. Test procedures are automatically controlled by the microprocessor. Operation procedures are intuitive and simple. Adopt a magnetic stirrer, it is safe, reliable, delicate, and there is less noise during test procedure.
