Review: Great value and accurate enough for insulation tests - This is a great little instrument for the cost. I found it very accurate. Maybe not rugged enough for everyday use, but very accurate and great for testing quickly when you don't need to drag the expensive MFT tester out quite yet. I would recommend as a second insulation test instrument to an MFT. Buy a good zip up case for it large enough to take a few sets of leads. Edit- A year later I still tend to grab this meter first before my Megger MFT. Continually impressed by it. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | UNI-T | | Colour | black | | Item dimensions L x W x H | 15 x 10 x 7.1 centimetres | | Item weight | 0.89 Kilograms | | Power source | Battery Powered | | Style | Digital | ## Product Details - **Brand:** UNI-T - **Colour:** black - **Item weight:** 0.89 Kilograms - **Power source:** Battery Powered - **Style:** Digital ## Images ![Insulation Resistance Meter UT501B - Image 1](https://m.media-amazon.com/images/I/510mK4sC9JL.jpg) ![Insulation Resistance Meter UT501B - Image 2](https://m.media-amazon.com/images/I/41k6T+CLrgL.jpg) ![Insulation Resistance Meter UT501B - Image 3](https://m.media-amazon.com/images/I/41gw1OT5aPL.jpg) ![Insulation Resistance Meter UT501B - Image 4](https://m.media-amazon.com/images/I/41YfR2K1yEL.jpg) ![Insulation Resistance Meter UT501B - Image 5](https://m.media-amazon.com/images/I/31b40+eKszL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice. *by D***. on 26 April 2026* Nice size, easy to use.
