Feature:

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.

 

Applications
