Here's how some of our customers use this product...

Multi-Gas Detector for Firefighters

The Background: Our customer is a fire department which seeks to replace the personal multigas detectors they are currently using.

The Problem: The main issue the department is having with their current personal multigas detectors is the short battery life. The detectors often have to be recharged during a shift causing the department to lose confidence in their ability to have the detectors working when they are needed.

The Solution: We recommended the BW Technologies GasAlertQuattro multigas detector as it has flexible battery options, either a field replaceable rechargeable battery or an alkaline battery pack so the unit can remain operational for the entire day.
