AstroAI Digital Multimeter and Analyzer TRMS 6000 Counts Volt Meter Ohmmeter Auto-Ranging Tester; Accurately Measures Voltage Current Resistance Diodes Continuity Duty-Cycle Capacitance Temperature

Great product, just what I needed. I appreciate the wide variety of measurements it can do, all for a bargain price.

Wonderful tool for the price. Durable, reliable and relatively easy to use

As someone who has carried and used a dmm as a necessary tool for decades, this is above average for occasional use. If you know how to use one. And in reality, good for the price. No, it's not a Fluke, but for 90% of what you use one for, it works fine and it's extremly inexpensive. Sample size of one, it was decently accurate when checked on the Volts, Ohms and Current scales. I measured various start and run capacitors and the readings were plausible. 1% resistors measured within 1%. I asked the vendor about the crest factor for the TRMS readings and they said it was 1.414. So I would be careful with readings of non sine waveforms, VFDs, servo drives, etc. The thermocouple readings are only in whole degrees, so perhaps indicator quality. I have a few gripes like the auto display and shutdown timeouts, but those are a pain on many dmms. Oh, and excessive beeping. I _know_ when I'm switching functions. The unit is supposed to have Cat II and III safety, but this depends on some fuses which are inobtanium in the US. I'm going to ask the vendor about a source. When checking 4-20mA automation signals it's really easy to touch the wrong terminal and blitz the .4A specialty fuse. The leads are short and PVC, but you can fix that. I don't have a means to check frequency and duty cycle handy. Now, retired, it should meet my needs. That is, I'm not going to return it and buy a Fluke. If I was working, I probably would.So my rating would have to be the famous "Good for the money". Spare fuses is an important issue working around 480 V to keep the Cat ratings.Construction seems adequate to me, you should treat your meters carefully. Oh, and one final thing.The magnet strap hanger is worth it's weight in gold working on equipment. I think Fluke's costs more than this meter.Update: Contacted the company, they said they would send a spare. This was a nice gesture, but in industry, to issue or approve the meter for a maintenance crew, it would be manditory to have spares available. It's a special part and the high current interrupting capability is needed for safety and to maintain the CAT rating. An ordinary fuse, if you could find one that fits the holder properly, might maintain an arc in an inductive circuit, destroying the meter and possibly starting a fire or injuring someone. Not as likely in residential power but, at 480 V and above, such things happen.

Is there better on the market? Yes. Do you likely need it if you are reading this review? Prob not.Great price and so far has been accurate and stable. The magnet isn't super strong, I wouldn't trust it though.

The old meter i had did not do what i needed so i searched on Amazon and this seemed to a really good option that was not that expensive. After buying it I am glad i got this one, overall it is a lot better built unit than the old one. It is a good meter accurite and rugged. The probes and the connectors are very stout and stay in the meter which the old one when turned on its side they fell out.
