SH124 automatic volume resistivity tester is designed and
manufactured according to the requirements of the People's Republic
of China power industry standard DL/T421-2009 and the national
standard GB/T5654. It is used for measuring the volume resistivity
of liquid media such as insulating oil and fuel oil.
SH124 automatic volume resistivity measuring instrument adopts
MCS-51 series MCU as the system control core, color LCD display,
Chinese man-machine dialogue, guide operation, the measurement
process is fully automated (automatic cup change, automatic shift),
and rolling storage of 200 test data;
And combined with modern new technology developed from.
The whole equipment of advanced design, reasonable structure,
simple operation, safe and reliable, is the contemporary technology
level of same sort products at home and abroad the highest
performance index, the most perfect resistivity tester,
particularly useful in the application of oil monitoring, power
sector test results accord with national standard DL421-91 the
insulating oil volume resistivity measurement.
