BW Flex4 Multi Gas Detector
The BW Flex is a serviceable multi gas detector with sensors for LEL (filtered and catalytic), Oxygen (O2), Hydrogen Sulphide (H2S) and Sulphur Dioxide (SO2) that will show the user real-time readings if there is a presence of gas. With the ability to connect your monitor to a mobile phone or smart device, the BW Flex allows you to access your gas monitor readings from anywhere.
With one-button operation and a clear, easy to understand display you can be assured the Flex is very easy to use. Access the menu with a single button press. Simultaneously detect gas in several applications with the confidence that the Flex is a reliable gas detector and will withstand tough environments.
As standard the BW Flex multi gas detector comes with a USB charging cable. It has a great battery life and is designed to run on a battery of 15 hours of use for around 40 days. This minimises downtime greatly and even if the unit needs charged then this should only take around 4.5 hours.
