The Senko personal gas monitor is very robust and can take a beating as you wear this in the field. The display is of good size, easily readable, and bright enough to see during the day in sunlight and night. There are multiple audible alarms to choose from and sound is loud to hear even around heavy machinery. Great bit of kit.

While Blackline have gone fully smart with the G7 and it certainly has a quality, high-tech feel. For organisations where safety and the gathering and processing of data is important, the G7 is difficult to ignore.
