Review on Instruments MQ 500 Including Lightweight Waterproof by Keith Farra

This light measurement device is everything I could ask for in an industrial and scientific tool... Thanks to my knowledge gained in practice, I can say confidently that this lightweight waterproof instrument is versatile and very accurate. Its various measurement modes and easy-to-read display make it ideal for use in the field as well as the lab. the only con is that it doesn't come with a carrying case, but that's a minor issue given its overall performance..
