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.
