Review: Best meter for the money - Very nice meter. I did not everything I would use the NCV feature on this meter but had to change a tankless hot water heater and wanted to make sure that power was actually off. Just held the meter to the the wire going to the unit and verified it was off. No reason to use the leads. Also noticed this works with USB cords as well to see if they have power at the end. I also work on analog power supplies which will have large capacitors on them. This unit is able to measure these which my old meter would not. So far I am very pleased with this meter.
Review: good meter for $53 - all meters are good at measuring voltage, but my old meter wasn't very good at measuring capacitance; this one is much better

## Questions & Answers

**Q: I'm finding conflicting information. does the ut139e have a black ebtn display like the ut139s?**
A: Hi, the UT139e has a regular display, black numerals over a light background. The UT139s has the black EBTN display. I have the “e” model and it’s fine, but I can see how the reverse contrast background might be more legible under certain lighting conditions.

### ⭐⭐⭐⭐⭐ good meter for $53
*by H***S on July 2, 2025*

all meters are good at measuring voltage, but my old meter wasn't very good at measuring capacitance; this one is much better

### ⭐⭐⭐⭐ It works well for my purposes.
*by J***. on December 31, 2025*

Good overall meter for occasional use. Sometimes in sunlight, the display will wash out, but so do most digital meters. Easy to use if you have ever used a VOM. Several features on the meter are yet to be explored. I purchased the meter to troubleshoot the CAN Hi network on my Volvo. The meter met the challenge.
