Digital Micro Ohm Meters UNI-T UT620B Low Resistance 10uohm Four-wire Measurement Resistance Meter Wire Length Tester
Digital Micro Ohm Meters UNI-T UT620B low resistance 10uohm Four-wire measurement resistance meter wire length tester
Applications:
Testing the resistance of metal coating, electromotor, and the winding resistance of small-sized transformer.
Point of junction of earthing system; the integrity of welding contact; breaker and switch; the connection of
spacecraft and the track; amphenol connector and conductor jointing; multi-cell battery; the generatrix of
switchboard; contact resistance of component like relay; metallic material; conductor resistance of wires and
cables; the ground resistance of the PEM LK of vessels, vehicles and aircrafts.
Features:
1. Low resistance range: 0.5mΩ~6kΩ;
2. Tesing 10A to increase the accuracy;
3. The minimum resolution 1 uΩ;
4. Bacis accuracy: 0.25%, four-wire testing;
5. Top and bottom testing, making it convenient to classify component, and judge automatically whether the object is standard or not;
6. Unique function of designing wire length , the unit meter and inch can be changed freely;
7. Chargable battery inside, long working life;
8. The data can be storage, read, and deleted. Data storage is 1000
9. USB interface.
