Review: electrical components, very important to check item before installation, for safety reasons. - Item arrived on time no damaged to component. Good quality product, when installed on customers machine it worked very well, the client was very happy with the result, and was able to operate his equipment much better. I would do business again with this Seller. Review: Great item very accurate and works well. - Using this item on my Hi-Fi distribution board to monitor its load. Was a bit sceptical on how accurate this item would be but after testing using my Fluke multi meter I was surprised with the results. The voltage was with in 1 volt of each other and the currant on several tests came within 100 ma. Very impressive. The display is bright and clear with voltage in red and currant in green. A round version would be a good alternative as drilling a hole would make for an easier installation. Highly recommended. ## Features - 【Wide measuring range】Voltage: AC 80~300V, Current: 0~100A, with high accuracy of 1% ± 2 digits.

Read my comment. *by S***Y on 27 December 2025* Frequency very accurate when compared to a mains frequency live source It seems to display things like this: Anything between 50.00 and 50.09 Hz will read 50.0, anything between 50.10 and 50.19 will read 50.1. etc etc. Great purchase. Very pleased. Voltage agrees within 1 volt of my Multi Function Tester. --- ## 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.th/products/110420909-ketotek-digital-voltage-current-meter-panel-ac-80-300v-100a](https://www.desertcart.co.th/products/110420909-ketotek-digital-voltage-current-meter-panel-ac-80-300v-100a) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-07-04*
