I bought it primarily for the battery testing facilities as we were having problems with some items [grandkids toys and other "smart home" items. We were changing battery sets frequently so thought I'd get a meter to check the status of each individual battery rather than block change them out. I chose this model from the reviews, the price, and the simple switch for choosing the test function needed. I have only used it for resistance and battery checking to date but it paid for itself within a short time as a relation has a holiday let and routinely has to check batteries for the fire regs. Using the meter allowed faulty cells to be replaced individually, saving money each time. I bought a second one as a gift and left it at the holiday let. Very simple to use and a nice clear display. The associated user manual is small but pretty comprehensive with some real life usage examples. My grandson likes to help with the testing [a clear red or green light depending on the voltage of the battery being tested]. One word of caution - the test leads have a very sharp prong at the end so be careful. ## Features - APPLICATIONS: Auto Ranging for accurate measurement of AC/DC voltage to 600V, Current to 10A, Resistance to 40MΩ. Tests Continuity, Capacitance and Diodes. - BATTERY VOLTAGE TESTER: 3 Voltage modes, Designed to test 1.5V, 9V, 12V Batteries. Multimeter light turns red for low voltage and green for enough voltage. - NON-CONTACT: Fully safe non-contact voltage testing with sound and light alarms. Uses NVC function to detect high voltage with red alarm light. - EASILY OPERATED: Backlight and flashlight functions allow it to be easily plugged in. LCD display comes on. - SAFETY: Double ceramic fuse which is anti-burn and protects from overloading. The silicon protection case protects it from damage. 3 Years provided by AstroAI. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08DHHJPS1 | | Best Sellers Rank | 10,454 in DIY & Tools ( See Top 100 in DIY & Tools ) 12 in Multi Testers | | Brand | AstroAI | | Colour | Green,Red | | Country Of Origin | China | | Customer Reviews | 4.7 out of 5 stars 6,340 Reviews | | Item Dimensions | 14.9 x 7.1 x 3.5 centimetres | | Item Weight | 219 Grams | | Item dimensions L x W x H | 14.9 x 7.1 x 3.5 centimetres | | Item weight | 219 Grams | | Manufacturer | AstroAI | | Manufacturer Part Number | M4K0R | | Maximum Operating Voltage | 600 Volts | | Measurement Type | Multimeter | | Model Number | ASIM4K0R | | Power Source | Battery Powered | | Power source | Battery Powered | | Style | Safety | | Style Name | Safety | | UPC | 810074980166 | | Upper Temperature Rating | 40 Degrees Celsius | ## Product Details - **Brand:** AstroAI - **Colour:** Green,Red - **Item weight:** 219 Grams - **Power source:** Battery Powered - **Style:** Safety ## Images ![AstroAI TRMS 4000 Counts Digital Multimeter, Auto-Ranging with NCV, Backlit | Volt Meter Tests 1.5V/9V/12V Batteries, Voltage Tester Measures Voltage, Current, Capacitance, Resistance, Continuity - Image 1](https://m.media-amazon.com/images/I/71TQq1ZlPHL.jpg) ![AstroAI TRMS 4000 Counts Digital Multimeter, Auto-Ranging with NCV, Backlit | Volt Meter Tests 1.5V/9V/12V Batteries, Voltage Tester Measures Voltage, Current, Capacitance, Resistance, Continuity - Image 2](https://m.media-amazon.com/images/I/81KuDe0YJ9L.jpg) ![AstroAI TRMS 4000 Counts Digital Multimeter, Auto-Ranging with NCV, Backlit | Volt Meter Tests 1.5V/9V/12V Batteries, Voltage Tester Measures Voltage, Current, Capacitance, Resistance, Continuity - Image 3](https://m.media-amazon.com/images/I/71EtgrP+7eL.jpg) ![AstroAI TRMS 4000 Counts Digital Multimeter, Auto-Ranging with NCV, Backlit | Volt Meter Tests 1.5V/9V/12V Batteries, Voltage Tester Measures Voltage, Current, Capacitance, Resistance, Continuity - Image 4](https://m.media-amazon.com/images/I/71pZWZrM4qL.jpg) ![AstroAI TRMS 4000 Counts Digital Multimeter, Auto-Ranging with NCV, Backlit | Volt Meter Tests 1.5V/9V/12V Batteries, Voltage Tester Measures Voltage, Current, Capacitance, Resistance, Continuity - Image 5](https://m.media-amazon.com/images/I/81f6jWu10HL.jpg) ## Questions & Answers **Q: How sensitive is the NCV feature?** A: I called it a name and it still works. It detects LED voltage on Christmas tree lights from about 5 inches away... you may find your meter has feelings, but mine seems to not care about sensitivity.. it just indicates voltage is present. **Q: Do the Battery Test selections test under load?** A: The M4KOR model does the 1.5v - 9v - 12v battery tests each is under a small load, and does test the battery voltage as part of the DC volts ranges. The M6KOR model does NOT perform battery tests under load, but does test the battery voltage as part of the DC volts ranges. **Q: Would you choose this model or another for automotive diagnosing?** A: To answer your question I'm a master Automotive technician most of the people in the business use flukes but our use these ones because they are accurate and work just as good as the fluke when it comes to Automotive Diagnostics. There is nothing you can't do with this digital multimeter that you can do with a fluke **Q: I have been trying to measure the ac/dc amps with this but doesn't work. i wanted to know if i am missing something or its actually faulty?** A: Make sure you have the leads in the proper slots or ports for the amperage reading. ## Customer Reviews ### ⭐⭐⭐⭐⭐ all the features you need, *by M***S on 14 April 2026* spot on, for automotive use it is great, battery voltage test with colour led, ohms test being auto ranging is perfect, very easy to use, ### ⭐⭐⭐⭐⭐ Paid for itself on saved batteries *by B***Y on 11 September 2025* This is great for home use if you use a lot of batteries.

He has found it easy to use and so far accurate. It's the right size for holding in the hand and has a clear readout. So far the quality seems good. ## Frequently Bought Together - 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 - AstroAI 8Pcs Multimeter Test Leads Set with Alligator Clips, Plunger Test Mini Hooks and Test Probes 1000V 10A CAT III & CAT IV 600V for Fluke, KAIWEETS, INNOVA Multimeter, Voltmeter, Clamp Meter - Hard Case Replacement for AstroAI Digital Multimeter Volt Meter by Aenllosi (for 6000 Counts) --- ## 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.co/products/235279801-astroai-trms-4000-counts-digital-multimeter-auto-ranging-with-ncv](https://www.desertcart.co/products/235279801-astroai-trms-4000-counts-digital-multimeter-auto-ranging-with-ncv) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-08-05*
