Product Details

What Makes the EEC-31 Hipot Tester Different

Most entry-level electrical safety testers cover AC Withstand testing and nothing else. When compliance requirements change, or when a new product line introduces DC or insulation resistance testing requirements, you would need to purchase additional instruments and train operators on additional equipment. The EEC-31 eliminates that problem.

AC Withstand (3 KV / 10 mA), DC Withstand (4 KV / 5 mA), Insulation Resistance (4 KV / 200 GΩ)

Productivity:
3 Test Memories, Charge LO
Dimensions:
(W × H × D) 215 × 88.1 × 300 mm

★★★★★
Does what it says
Bought 3 to replace our old separate testers. Freed up bench space across our lines. Setup was quick. Will probably order more if we expand.

★★★★★
Consistent readings
Using these for battery insulation testing. Ordered 2 for different stations, readings are consistent across both. IR range covers what we need.

Covers our compliance tests
AC hipot, DC hipot, and IR in one unit. Saves time not switching between instruments. Calibration has been stable. Does what we need it to do.

Farah · Lab Technician Mar 25, 2026
★★★★★
Good for smaller labs
Small lab, didn't need three separate testers. This covers AC, DC, and IR. Came with test leads and a factory calibration report. Works as expected.

★★★★★
Simple to operate
We use it for withstand and insulation resistance checks on transformers. Rotary knob is easier than menu-based testers. No issues.

★★★★★
Ordered 4 units
Bought 4 to equip our production line. Delivery was faster than quoted. Operators picked it up quickly, and the saved test memories mean they don't re-enter settings each shift. All units running fine.

★★★★☆
Manual needs more detail
Tester works fine, no performance issues. User manual could use more detail on setup. Figured it out but worth noting.
