15 ～ 100 ℃ Automatic Volume Resistivity Tester Accuracy ± 0.5 ℃ 2.0mm Spacing GB/T5654

SH124 Automatic volume resistivity tester

The SH124 automatic volume resistivity tester is designed and manufactured according to the requirements of the power industry standard DL/T421-2009 for measuring the volume resistivity of power oil in the People's Republic of China. It is used to measure the volume resistivity of liquid media such as insulating oil and fire-resistant oil.

The SH124 fully automatic volume resistivity measuring instrument adopts MCS-51 series microcontroller as the system control core, color LCD display, Chinese human-machine dialogue, guided operation, and the measurement process is fully automated (automatic cup change, automatic gear change), and 200 test data are stored in a rolling manner; And developed by combining modern new technological methods.

The entire instrument is designed with advanced technology, reasonable structure, simple operation, safety and reliability. It is a resistivity tester with high technical level and complete performance indicators for similar products at home and abroad. It is particularly useful for oil quality supervision in the power sector, and the test results comply with the national standard DL421-2009 "Determination Method for Volume resistivity of Electric Power Oil".
