Review on Portable Detector Hembisen 4 Gas Monitor by Mark Grey
"Unexpected Gem - Earbud-like Detector
This "Portable Detector Hembisen 4 Gas Monitor" may not be an earbud headphone but it's small and light like one. Through trial and error, I found that its sensors are quite accurate, giving me peace of mind while working in potentially dangerous environments. Plus, the long battery life is a big plus. The only con is that it may not fit as comfortably in your pocket as a standard pair of earbuds. Overall, this portable detector is a great addition to any safety or environmental toolbox..
- Easy-to-use portable monitor that detects four gases: oxygen, carbon monoxide, hydrogen sulfide, and combustible gases.
- Requires regular calibration to ensure accurate readings.
