Digital Clamp Meter

Professional Heavy Duty AC, DC/AC T-Rms Auto-Ranging Clamp Meters



Our new DT-3370 Series Heavy Duty Digital Clamp meters offer all the features you need to fit the way you work. It provides a full range of state of-the-art features to meet even the most demanding job requirements. The body and jaw perfectly fits in your and into tight areas of work. Meter controls are positioned so that current measurements can be done with one hand.

All the three clamp meters have improved based features such as a large, backlit display, true-RMS standards, CAT-IV safety ratings and a durably constructed housing. Have increased reading capability of 1000A and 1000V AC and DC.

These clamp meters confirm to CAT-III 1000V, CAT-IV 600V and are TUV & GS Approved. They confirm to EMC & LVD, EN:61326, EN:61010-1, EN:61010-02-031
