Review on Portable Detector Hembisen 4 Gas Monitor by Derek Fisher

Using this tool, our team found that the Hembisen 4 Gas Monitor is a fantastic addition to our tool kit. Its portability is a huge plus and its accurate readings make it a reliable detector .Its LCD screen is easy to read and the alarm system provides added safety features. The only con is that it doesn't have the best battery life. Overall, we highly recommend this product to any team in need of a gas detector for work..
