Insulation Oil Dielectric Strength Tester（Oil Tester）,
Gas Chromatographic Analyzer |
|
|
They
are divided into two types: automatic and full
automatic, in keeping with 《Insulation oil automatic
dielectric strength testing method 》. They are
portable and of the latest designs; they fully
overcome the shortcoming that the intergraded
oil tester is easily obstructed by the puncture.
Automatic operation enables the stirring, stewing
time automatically set and so does the print times.
The speed of voltage increase which is adjustable
is about 2kV-3kV/S.They are suitable for power
supply departments and petrochemical engineering
departments. At the same time, this company also
produces and provides intergraded oil tester which
had already solved the shortcoming.
HRIIJ is the Automatic
Oil Tester. HRIJJ is the full Automatic Oil Tester.
