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 ## Features - Easy to use electrical tester kit. Value pack includes: UT139C voltmeter digital, test leads (pair), temperature probe, paper manual, eManual (free download), gift box ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08V4RTJ8N | | Brand | UNI-T | | Brand Name | UNI-T | | Customer Reviews | 4.7 out of 5 stars 45 Reviews | | Item Weight | 1 Pounds | | Item weight | 1 Pounds | | Manufacturer | UNI-T | | Model | UT139C | | Part Number | UT139C21 | | Power Source | Corded Electric | | Power source | Corded Electric | | Specification Met | UL | | Specification met | UL | | Style | Digital | | Style Name | Digital | | UPC | 767461830521 | ## Product Details - **Brand:** UNI-T - **Item weight:** 454 g - **Power source:** Corded Electric - **Specification met:** UL - **Style:** Digital ## Images ![UNI-T True RMS Digital Multimeter UT139C Auto/Manual Range 6000 Counts NCV Continuity Buzzer Bandwidth Measure AC DC Voltage AC DC Current Resistance Capacitance Frequency Temperature Duty Cycle Diode - Image 1](https://m.media-amazon.com/images/I/71RkRQceBUL.jpg) ![UNI-T True RMS Digital Multimeter UT139C Auto/Manual Range 6000 Counts NCV Continuity Buzzer Bandwidth Measure AC DC Voltage AC DC Current Resistance Capacitance Frequency Temperature Duty Cycle Diode - Image 2](https://m.media-amazon.com/images/I/71xtGMMbXvL.jpg) ![UNI-T True RMS Digital Multimeter UT139C Auto/Manual Range 6000 Counts NCV Continuity Buzzer Bandwidth Measure AC DC Voltage AC DC Current Resistance Capacitance Frequency Temperature Duty Cycle Diode - Image 3](https://m.media-amazon.com/images/I/617R4DUCq1L.jpg) ![UNI-T True RMS Digital Multimeter UT139C Auto/Manual Range 6000 Counts NCV Continuity Buzzer Bandwidth Measure AC DC Voltage AC DC Current Resistance Capacitance Frequency Temperature Duty Cycle Diode - Image 4](https://m.media-amazon.com/images/I/71fAYCxhPnL.jpg) ![UNI-T True RMS Digital Multimeter UT139C Auto/Manual Range 6000 Counts NCV Continuity Buzzer Bandwidth Measure AC DC Voltage AC DC Current Resistance Capacitance Frequency Temperature Duty Cycle Diode - Image 5](https://m.media-amazon.com/images/I/7124lSSriPL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best meter for the money *by J***N on 29 March 2025* 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.

So far I am very pleased with this meter. ### ⭐⭐⭐⭐⭐ good meter for $53 *by H***S on 2 July 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 31 December 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. ## Frequently Bought Together - UNI-T Digital Multimeter Tester UT139C, Voltage Meter Tester Capacitance Meter Frequency TRMS 6000 Counts Auto/Manual Ranging - PINECIL – Smart Mini Portable Soldering Iron, Small - SRA Solder 135 Rosin Paste Soldering Flux For Electronics, No Clean Flux Made for Lead and Lead-Free Solder Circuit Boards and Copper Electrical Wire - Safe Clean Residues with No Goopy Mess (2oz Jar) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/415061393-uni-t-true-rms-digital-multimeter-ut139c-auto-manual-range](https://www.desertcart.de/products/415061393-uni-t-true-rms-digital-multimeter-ut139c-auto-manual-range) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-11*
