Features

UT139 Series digital multimeters are newly designed to offer users better performance and higher safety rating. Totally over-load protection and unique structural design make it new type of multimeter with high performance/ price ratio and a best choice for electricians used in electrical maintenance and repairing.
1. True RMS for the whole series;
2. Measure signals with varied frequency (VFC);
3. Measure large capacitance up to 100mF;
4. Optional AC/DC 60A current clamps in different models to measure current up to 60A(1mv=1A);
5. NCV designed for the whole series, a necessity for electricians;
6. AA1.5V*2(5#) battery, easy for users to purchase and replace;
7. Soft rubber holster is easy  to stand 2m drop;
8. Optional magnetic hanging strap offered to facilitate tests in special location;
9. Fast to replace fuse, just by opening battery cover;
10. Reliable with use of internal 2PCS fuses with high-breaking capacity;
11. Protection against 600V input/1 minute from misconnection;
12. Safety Rating: CAT III 600V.
