VC60B Digital Insulation Resistance Tester, Electrical Megaohm Meter with 250V/500V/1000V Test Voltage Testing Insulation Resistance IR 0.1MΩ~2GΩ, Multimeter Measure AC Voltage

Performs on par with tools way ahead of it in price.

After trying to diagnose an instrument that would fail indicating a leakage across the poles, I finally opted to get this little machine in lieu of my generic Fluke multimeter that maxes out at 50 megohm.Had it figured out in no time! Showed 140 megohm between two of the poles, eureka! Was able to clean and replace insulators until it maxed this meter out at 2 G ohms. Instrument works like a champ now!Box is in Chinese, but if you're buying a device like this, you won't need instructions. Display even shows you which sockets to plug leads into for each setting if you're confused.I'm using this device in a professional setting and it's been fantastic. I could not justify spending hundreds or thousands on a Fluke for a device I won't need often.Oh, and do yourself a favor and dispose of the 6 heavy duty AA batteries that come included in the package. All heavy-duty batteries leak eventually, and when they leak, they leak acid. In a device like this that may sit unused on a shelf for many months, you don't want heavy duty batteries in there.

For an inexpensive megaohm tester this did what I was looking for. Our AC quit working and I wanted to check out the compressor to see if it was the problem ( I didn't want an AC repair guy to possibly tell me the compressor was bad when it wasn't and have it cost me thousands). You also need a multi-meter, but between the two I was able to verify the compressor was in great shape. I later tracked the issue to a loose connection in the fuse box and fixed it for free. I would have given it another star for better instructions, but these work just like any other and I figured it out pretty quickly. Is this a professional grade tester? No, but for occasionally testing motors and such, does the job for not a lot of money.

I compared this tester to a older megger I had and they agreed so I believe it is reasonable accurate. I like to test old motors and such before putting into service and it works well for that. Very happy with the product and price.

This is an effective entry level insulation resistance tester. It comes with a pair of leads, insulated alligator clips, and enough batteries to get started.The included leads are very flexible and about 3 feet long. The probes are very sharp and include caps to keep them sharp. The banana plus are better quality than I expected, they have four leaves and they fit firmly into the jacks. The included alligator clips just clip on the tip of the probes with a friction fit that is tight and it seems to maintain a good connection.I tested the device on a couple of high resistance resistors that I had lying around and everything seemed to be in range of the devices stated tolerance. I also tested a couple of known good electric motors that I had on hand and everything read exactly as it should.I was also impressed with the instructions included with this tester. This was my first time using an insulation tester and the instructions were translated well enough for me to figure out the basics and start using it.Overall, this insulation tester is perfect if you just need something for a few tests. The price is a great value for what you receive.

I was very happy to receive this and use it in my electronics hobbyist projects. I had seen BigClive on YT demonstrating the use of these to check motors and safety tests, etc., so i wanted one to use for similar stuff.It certainly doesn't disappoint.It has been easy enough to figure out the basic operation of this, but i will have to bury my head in the manual for deeper stuff. One of the guys on here says he tested it against his old Megger and it came out very comparable, so i will take his word for that. I don't need mine to be critically exact anyway for my projects. I just need to know if some item might break down or not....and this does that perfectly for me. It will test out if there is any breakdown on any sections of a stator or a rotor. Plus it will test any lightning arrestor's etc. And a bunch of other things i might want to play with and test out.I love having the use of this, and it seems a pretty decent price, too. And they even include batteries.

The media could not be loaded. Overall, this appears to be a megaohm meter That is fairly accurate. The only question is at 1000V it reads 1.2 megaohms higher if anything it should be lower because of the leads possibly bringing the value down.I will reach out to the manufacturer and ask why it reads 2.2 megaohms with a one megaohm resistor on the 1000V setting.Otherwise, this meter should get the job done for General purpose assessment of motors and HVAC compressor motors.

A great piece of equipment by SKYCENX. It’s a multifunction meter for accurate insulation resistance testing, it’s an electrical megaohm meter and multimeter to measure Ac and DC voltage. It is user friendly and even offer visual cues and guidance to properly insert the leads for accurate measurements. A great tool for professional or handyman toolboxes. Seems to be very accurate at measuring resistance, ohms and electrical voltage, making it a reliable tool at a very good price.
