The Handheld Battery Powered Contact Resistance Tester is designed for field engineers who need a compact instrument for quick low-resistance measurements.
The instrument integrates the battery, high-current source, measurement circuit and display into a portable enclosure.
It is suitable for maintenance teams that frequently travel between substations and industrial sites.
Some current handheld products provide selectable currents up to 200A, 0.1 μΩ resolution, internal storage and fast measurement times.
Q: How many tests can a battery-powered tester perform?
A: This depends on the battery capacity, test current, test duration and operating conditions. Some current models advertise hundreds of tests per charge.
Q: Is a handheld tester accurate enough for maintenance?
A: A properly specified professional micro-ohmmeter can provide the required accuracy for its intended testing range. The exact accuracy should be checked against the model's calibration specification.
