Laboratory Gas Detection

The laboratory can be a dangerous place. From trip hazards, flammable materials and even bio-hazards. Furthermore, there are many aspects of risk minimisation that need to be considered to create a workplace that is both safe and compliant with health and safety legislation. One particular hazard that is common to many types of laboratory, from the life sciences, to physics research, is the hazards posed by gases.

Many of our gas detectors are based upon the 2-Wire safe area addressable gas detection system with detectors for over 400 different gases. This system has a unique design that makes it quick and easy to install and can then be used for continuous gas level monitoring.

These devices utilise addressable technology, which means they can be integrated with additional detectors or networked equipment. This includes devices such as our innovative Room Status Indicators, which can be installed outside the laboratory and have a visual display showing gas concentrations inside the lab and whether or not it is safe to enter. A single status indicator can display the output from up to 8 other detectors and devices. With a colour change RGB display and internal sounder, this is the perfect solution for room entry control with clear unambiguous messages.

he two-wire design for these devices means, you have one two core cable for both power and communication. Minimal cabling but offering maximum flexibility as the detectors themselves also have interface points built in for other devices.

These can include:

• Call points
• analogue signals
• relay interlocks, and much more.

It also reduces the risk of wiring mistakes as the 2 core cable connection has no specific polarity requirement. Multiple detector monitoring, alarm and interlock solutions can be quickly and efficiently configured. This makes our system especially desirable where it is recommended to have multiple detectors at different heights in the laboratory with audible visual warnings, gas interlocks and secondary monitoring.
