Date published 18.02.2026
UT513B/UT513C are digital high-voltage insula?on resistance
testers with high-voltage output ranges of 250V, 500V, 1000V,
2500V, and 5000V. They are commonly used and essen?al
instruments for power, telecommunica?ons, meteorology,
computer rooms, oil fields, electromechanical installa?on and
maintenance, and power supply departments of industrial and
mining enterprises.
