Personal Gas Detectors
Single Gas Detectors
When sourcing a personal gas detector, start with the number of gases you need to monitor.
Single gas detectors are used when there’s only 1 hazardous gas present such as carbon monoxide in gas boiler plants.
Confined Space Entry Detectors
The PS200 detects the most four common gases that workers face in industrial environments – Oxygen, carbon monoxide, hydrogen sulphide and combustible gases.
Most confined space gas detectors are fairly limited with the choice of gases they can detect.
If you need to monitor 5 gases or more exotic gases like ammonia or hydrogen cyanide, then a multi-gas detector is required.
Multi-gas detectors are bigger in size and often pack more useful features than single and confined space detectors.
Features include lone worker alarms, datalogging, and extra rugged housing.
It’s this configuration that offers a much wider gas library which could include an IR sensor for monitoring Carbon Dioxide and PID sensor for VOC detection.
How Long Will Batteries Last?
All gas detectors will have different battery life options.
Disposable gas detectors are available with a 2 year battery. Turn on the Protege ZM or the Clip4 and away you go without having to worry about recharging.
Most gas detectors are available with a rechargeable battery which should operate for the duration of a shift before it needs recharging.
If you want the convenience of longer operation between charges, you will need to buy a detector with low power sensors
How Long Will The Sensors Last?
Electrochemical are the most economical sensors and will run for 2-3 years. Some new oxygen sensors will last for up to 5 years.
PID lamps are slightly different:
- The 11.7eV lamp can measure the broadest spectrum of VOCs yet it has the shortest lifespan
- 10.6eV is the most commonly used lamp because it has a 2-3 year lifespan and offers a wide detection of VOC gases
- The 9.8eV PID lamp requires the lowest power and has the longest lifespan but is limited to the number of VOCs it can detect
