Typical gas detection questions answered by our experts
Is there a detector for gas?
There are many types of gas detectors available based on various measurement principles. Depending on the gas a certain type of gas detector would be selected that would be either a broad spectrum detector or a gas detector looking for a specific gas only.
What are the types of gas detectors?
Gas detectors come in various measuring principles from catalytic sensors, photoionization sensors, electrochemical, infrared and ultraviolet light. Selection of the detector would be dependent on the gas to be measured and also the budget as some of these technologies can be costly.
What is a fixed gas detection system?
This would be a gas detector that is used for environmental monitoring in a fixed location. Typically for an environment to be monitored there would be a single or multiple gas detectors fixed in place over the area of interest. The number of fixed detectors required wold be calculated based on the volume of air in that area. Our experts can help you in sizing the system by making a site survey or survey of plans or drawings.
How many types of gas detectors are there?
There are typically four main types of gas detector, these are Electrochemical, Catalytic, Infrared and Photoionization sensors. These types of detectors come in fixed and portable versions.
What is a 4 gas detector ?
This type of gas detector is a single device that will monitor 4 components simultaneously, these are typically:
- %LEL or the lower explosive limit which is a measurement of the lowest concentration of gas vapour that will burn in air, so essential this is a flammable gas detection.
- Oxygen measuring the %O2 in the atmosphere (Normal Air 20.9%).
- Carbon Monoxide measuring the CO level in the atmosphere (Normally 100ppb in Air).
- Hydrogen Sulfide or H2S which is a poisonous, corrosive and flammable gas.
Custom designed Gas Detection Systems
At JWI we recognise that every Industrial and commercial installation is unique, from over 35 years’ experience we know that fixed gas detection systems can only be as effective as the design and planning that goes into them. We work in close consultation with our clients to design the best customised system to meet the needs of their specific application. We provide help and guidance throughout the entire project from start to finish to make sure the optimum solution is provided for the client. This way you can get the most effective gas warning system for the specific needs of the project.
