Review: Good meter - This is a nice meter. It seems as well built as my old HD Beckman DMM, and that was the best there was in build quality..nicer than the F brand in my opinion. Mine came with a plastic case, a set of leads, and an extra negative lead that has an alligator clip. That's handy, because it lets me test in mid air. Just clip one wire, hold the other wire against the positive lead with one hand, hold the meter with the other and press the button. I thought I'd use the locking function more than I do, but it's actually easier to just hold the button. That lets you hold the lead and release the test button, which auto drains the voltage off the wires. If you just keep the leads hot, you can test, but with good and long wires, there's enough capacitance to hold a charge on the lines and give you an annoying shock. All in all, very happy. If you don't need more than 2000 MOhm at 1kV, this is a very good deal. No issue with battery drain, and not sure how you would, as the main switch seems to turn off power to everything. Review: I am very happy with this purchase - Purchased this for what I thought was a one time use, needed a 1000v megohmmeter to test cable insulation. Since receiving this product I was also able to retire my older multimeter. I did a lot of research prior to my purchase since I needed the tool for 1 job therefore not wanting to spend too much. This tool has all the features as other units costing $100's more, I am very happy with this purchase. ## Features - Autoranging digital megohmmeter with selectable 250 V, 500 V, and 1000 V DC test voltages for versatile insulation testing - Measures insulation resistance up to 2000 MΩ with a large dual backlit LCD showing both test voltage and resistance - Includes low resistance, continuity, and AC/DC voltage measurement functions for comprehensive diagnostics - Features automatic discharge after test, protective holster with stand, lock power-on, and data hold for convenience - Complete kit with heavy duty test leads, carrying case, and 6 AA batteries for immediate field use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000EWW2UA | | Best Sellers Rank | #155,694 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #27 in Insulation Resistance Meters | | Brand Name | Extech | | Color | orange and green | | Customer Reviews | 3.9 3.9 out of 5 stars (55) | | Global Trade Identification Number | 00793950382608 | | Included Components | Test leads, case, 6 AA batteries | | Item Dimensions | 7.8 x 1.9 x 3.6 inches | | Item Weight | 1 Kilograms | | Manufacturer | Extech | | Measurement Type | Ohmmeter | | Minimum Operating Voltage | 250 Volts (DC) | | Model | 380260 | | Power Source | Battery Powered | | Specification Met | (unset) | | Style Name | Standard | | UPC | 793950382608 | | Warranty Description | 1 year parts and labor | ## Product Details - **Brand:** Extech - **Color:** orange and green - **Item Weight:** 1 Kilograms - **Power Source:** Battery Powered - **Style:** Standard ## Images ![380260 Autoranging Digital Insulation Tester - Image 1](https://m.media-amazon.com/images/I/41InRsegbmL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good meter *by T***M on December 16, 2015* This is a nice meter.

The rest of the options still working good, but the most important one not. Really sad because that happened suddenly while I was using the tester in one of my projects. ## Frequently Bought Together - Extech 380260 Autoranging Digital Insulation Tester - Extech PRT200 Non-Contact Phase Sequence Tester - 25Ft Extra Long USB-Printer-Cable 2.0 for HP OfficeJet Laserjet Envy, Canon Pixma, Epson Workforce, Stylus, Expression Home, Brother, Silhouette Cameo, Dell Scanner Fax Cord --- ## 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.pt/products/14401374-380260-autoranging-digital-insulation-tester](https://www.desertcart.pt/products/14401374-380260-autoranging-digital-insulation-tester) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
