 2. Gas Detector: To Buy or Hire?

Gas Detectors available at One Point Survey - A Buyers Guide to Gas Detectors

Deciding you want or need a Gas Detector is the first step, next you will need to decide whether buying or hiring is best for you.

The answer is different for every individual and so there are some important things to consider before making the decision.

  • How often will the product be used? Buying a gas detector outright can be an ideal option for those who know that it will be regularly used as this will more than make up for the price. However, if you’re using it here and there for odd jobs perhaps it would be more cost effective to hire.
  • What is your budget? Buying expensive products outright might not be an option for some. Thankfully, there are plenty of options when it comes to Gas Detectors and many of them are affordable!

There are many different Gas Detectors available for use and so there is a lot to consider when trying to choose the one for you.  Here are some things to consider:

  • Application: Consider what you will be using the Gas Detector for, is it to feel safer in your home or for work? If you are working it is more likely you will use a portable Gas Detector! If you are looking to use it in the home you are more likely to use a fixed gas detector.
  • Gas Detection: What gas do you want your Gas Detector to be able to detect? Some detectors are able to detect multiple gases whilst others aren’t. If you’re in need of a product that can detect a specific gas, make sure that the one you are buying is able to detect it.
  • Experience: The product you should buy will depend on your knowledge and experience. If you are new to gas detection with limited knowledge you would be better off considering an easy to use gas detector such as the Crowcon T4!

4. Types of Gas Detectors

Gas detectors come in two main forms: fixed gas detectors and portable gas detectors.

Fixed gas detectors are typically mounted in areas you wish to be protected from gas and are then able to alert you to high volumes of gas should that occur.

Portable gas detectors are usually clipped to the belt of working personnel to monitor the area around them. These products will also alert their wearer to dangerous levels of gas being detected via flashing lights or alarms.
