UT278A Digital Clamp
Earth Ground Tester 1200Ω
UT270 series can quickly and safely measure the grounding
system without disconnecting circuit ground lines or the need of auxiliary
electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω.
UT275 can also measure leakage current up to 30A. These clamps ‘double
insulation design makes them durable tools for outdoor work and effective in
blocking interference signals from the environment.
Applications:
Grounding resistance measurement in electricity,
telecommunication, meteorology, oilfield, architecture and industrial electric
equipment.
Features:
1. Resistance limit alarm
2. Auto range
3. Low battery indication
