AstroAI Multimeter Tester, TRMS 4000 Counts Volt Meter Auto-Ranging Ohmmeter Digital 1.5v/9v/12v Battery Voltage Tester Measure Voltage Current Resistance Diodes Continuity Capacitance with NCV

Very pleasantly surprised by this inexpensive multimeter. I was not expecting a lot but was quite happily surprised by the ease of use, the large number of features, and the accuracy of the voltage, current, capacitance, and resistance measurements. It is compact and has good fit and finish. It is 4000 counts meter which is fine for electronics hobbyist use. For a beginner multimeter user, an electronics hobbyist, or just to have a spare meter, this is pretty nifty. The NCV feature is handy. The set of test probes seem to be of decent quality and come with those little plastic covers that cover everything but the tips (to prevent accidental short circuits).

I’ve owned more meters over the years than I care to admit, some dirt cheap, some that cost more than a car payment, and this little AstroAI unit holds its own. It’s sturdy, accurate, and easy to read, even for old eyes that have seen a few too many decades of tiny print and bad lighting. The auto-ranging and backlight features make quick work of household fixes and garage diagnostics. Is it a Fluke? No. But it’s damn close for a fraction of the price. The feel in the hand is solid, the readings are consistent, and it hasn’t glitched once in months of use. Throw in a set of better leads and maybe a small case, and you’ve got a go-to meter for just about any weekend project or light professional task. Bottom line , dependable, affordable, and tough enough to earn a permanent spot on my workbench

I purchased this meter as a back-up. This is an inexpensive multimeter that comes with a few extra features. Beyond the typical VDC, VAC, mA, Amps, Resistance and Capacitance readings, it also provides Non-Contact AC Voltage (NCV) and Live Wire AC Voltage detection. The construction is solid. The display backlighting is strong and works well. Note that the NCV detection is fidgety, though. Placing the NCV detector (located at the top of the meter) near an operational 120 VAC outlet, the meter would reliably indicate a "Low" AC voltage (green light) when it is near the outlet. However, it takes a lot of tiny meter position adjustments to get the NCV to indicate "High" AC voltage (red light) near the "hot" line of the AC outlet. The NCV operation is unreliable enough that I may just pull out the probes and plug them in. I subtracted a star from the final product rating as a result. I have included pictures of the meter's contents. The red/black meter probes come with a protective cap over the banana jacks - these will probably be lost within the first month of use. The meter probes are normally fully insulated, exposing a small sharp tip for probing circuitry. The same probes also have a removable sleeve (shown for the black probe) that can be pulled off to provide a longer "pin sticker" probe to insert into the back of Molex type connectors for readings. The 2xAAA batteries were already installed into the meter on delivery, with no protective tape to prevent electrical connection to the meter. So, I have followed the recommendations of other reviewers, and have replaced the installed cheap alkaline batteries with new Duracells just in case the original batteries may fail quickly (and possibly leak).

Just got it in one day. Initially poked myself with the probes while removing them. Thought they would have caps on them. My fault. Instructions were printed so small that I had to get a magnifying glass to read. Once I read the directions and tried it out I was amazed at the simplicity of this gadget. It goes to automatic and that's all that's needed. I can test resistance and voltage without twisting any dials. Large read out, flashlight, and convenience of the automatic/smart feature makes this the best meter that I have ever bought. My $75 meter gave out after 3 years. It was complicated with too many choices. So now I have this for $15 and it's all is in a case and fits in my pocket.

Good meter, well-featured and fairly priced. Comes with batteries (that have held up for nearly two years and still show 1.58v). For continuity tests, in addition to an audible tone, it also has an LED (green) that illuminates, which I've found useful when testing in a noisy environment. The leads store (clip) easily into a molded insert on the rear of the meter. It has a tiny (white) LED on the top/end of the meter to be used as a flashlight. A critique would be that the leads would benefit from being ~8" longer. A soft case would be nice, but perhaps not at this price point. The first unit I owned lasted ~2 years at which point it would no longer test continuity. Voltage tests still worked, though. The unit claims a 3-year warranty, so I sent an email to AstroAI (with my receipt attached). They responded within 24 hours with some troubleshooting tips (confirm both fuses good), leads inserted firmly, etc. I confirmed the meter remained inoperable for continuity tests. The next email requested a short video validating the condition, which I provided. Shortly thereafter, I received an email with an order number for the replacement unit they were providing. Great customer service! I own a few other AstroAI products and my experience with their Customer Service Team reinforces my intent to continue buying their products.

works fantastic . easy to use . great price

all functions checked out perfectly. very easy to use. display is excellent. I'm using it to trouble shoot electric guitars and to verify new components before installing them.

After less than a week of use, so far, so good. You can use most functions without cracking the manual. And speaking of the manual, it's pretty ok, too. Some grammar errors and some funny instructions, but none that make it hard to understand. The meter seems to be built well, the display is very easy to read - especially with backlighting. All in all, this meter provides good bang for the buck.
