Lomvum Digital Multimeter, 6000 Counts Electrical Tester AC/DC Voltage Current Detector, NCV, Resistance, Capacitance, Diode Electronic, Duty Cycle Tester

It has all the standard tests that you would see in a multi tester but it does have wider ranges in almost all of the standard tests. Not only does it have a standard diode and continuity test but it has the ability to test capacitors and transistors which some multi testers can do. Now for some of the extras. It has a non-contact ac voltage detector built into it so I no longer have to keep a separate probe for that. It has an accurate frequency tester which comes in handy. It has the ability to test temperature so I can find out if a component is extremely hot. It also has a nice infrared remote detector to actually see if your infrared remote control is sending signals. All in all this multitester has replaced four of my previous tools in my tool kit. I highly recommend this tester for its features and accuracy.

LOMVUM T28B is essentially the same as Richmeters RM118B. Pleased with the build quality. Test leads are not the best, but quite suitable. I was pleasantly surprised by the buzz without delays, like expensive multimeters. At first there were delays, but then I wiped with a degreaser and the delays disappeared. NCV is not entirely clear, but it is quite suitable for detecting an electric field and detecting a break in a wire. I managed to buy when it cost $ 23. Now it costs $ 30 :)). The disadvantages are the lack of an option to disable beep and power from 4 batteries instead of 2. In general, satisfied with the purchase. I recommend to buy. Thank you Lomvum!P.S.My review is for the model T28B, not the T21E. And I bought exactly the T28B model. For some reason, my review follows an incorrect link to the T21E model. I do not know this, a bug of the Amazon site or the seller of Lonvum. Please correct this so as not to mislead people. Thank!

Auto-Ranging Digital Multimeter, 6000 Counts Electrical Tester AC/DC Voltage Current Detector, NCV works as expected, except for the NCV. NCV does not function very well, it gives a false signal where there is no cable(romax) and nothing right at the outlet, lol. NCV need more work I suppose.Otherwise the meter works pretty good. Display is easy to read and selecting test mode is very easy. Great meter, less teh NCV. I would give it 5 star if not for the NCV.

It comes with the most used (required) features for amateur, educational and low voltage professional projects. Solid build and protective cover comes handy for workshop and field used. Please note this device is not recommended for voltages over 300V.

Pros: It performs very well at all functions. Meets all the specs listed. Even lights white LED's and is able to display the voltage value with no problems. Back light display is awesome. The magnet on the back is really helpful when you need both hands to perform readings. The continuity test latches quick and it is very responsive. Capacitance measurement has a very nice range and 4mfd takes about 7 seconds to get the reading. One of the best I have seen for this price point.Const: The range switch beep every time you change the position (This can be annoying for someone). It has ceramic fuses but those are rated 250v only and the input protection is limited; So the application of this meter is limited (No for electricians or work on the mains). But great performance for electronics or work inside home before the electrical panel. That is why the 5 stars.

for the price it is a great meter and very accurate. Fast shipping and very nice to have a meter of great price and quality

It works, just needed a volt ohm meter

I purchased this device to test a car battery for excessive drainoff at night. To my dismay upon receiving the unit neither the amp or miliamp channels work on the device. I've tried other wires thinking the ones it came with were bad. I've attempted to test small batteries and other electronic components alike. I get no reading. I will be refunding my money and going to a different product. Highly disappointed. do not buy!
