Might be a bit 'delicate'. - The meter is very small. You need a small cut out. The whole thing reeks of "cheapness", but it did work as best I could tell. I couldn't measure much current, but I think very little was flowing (we had problems). So I think it worked OK. But the plug for the power/voltage input pulled right off the board, left three pins sticking up. I was able to fix it, but be careful. The current sensor wires are pretty short (another reason I couldn't use it). So I need to make them a bit longer. ## Features - 【Dual Digital Display】This Hall voltmeter ammeter features a dual digital display, allowing simultaneous monitoring of voltage and current. - 【Wide Voltage and Current Range】With a range of DC 0-300V and options for 50A, 100A, 200A, or 400A, this voltmeter ammeter is suitable for a wide variety of applications. - 【Accurate Measurements】The hall effect sensing technology ensures precise and accurate measurements, providing reliable data for your electrical systems. - 【Easy to Read】The digital display is easy to read, with clear and bright numbers that can be easily seen even from a distance. - 【Convenient Installation】This voltmeter ammeter is designed for easy installation, with a compact size and simple wiring connections.
