Personnel who run the risk of exposure to ammonia routinely carry portable ammonia gas detectors. But with so many different gas detectors currently on the market, it can be difficult to determine which product provides the best and most cost-effective solution. This article covers the main considerations that should be made when purchasing portable ammonia gas detectors.
Portable Ammonia Gas Detectors: The Basics
Ammonia (NH3) is a common industrial gas hazard. It is widely used as a refrigerant gas and has many applications in the production of chemicals including fertilizers, plastics, and pesticides. Exposure to ammonia – either at high concentrations or over a long time period – can irritate the eyes and airways and has the potential to cause severe injury or even death.
In environments where ammonia is present, portable ammonia gas detectors are essential. These devices – carried by personnel – provide personal protection and the last line of defence to alert a user to dangerous levels of ammonia in the immediate area.
Gas detection technology is a highly developed field, and today there are hundreds of different portable detectors available which offer a huge range of functionality. But what factors should you be considering when buying a portable ammonia gas detector?
Reliability, Performance & Cost
Adequate performance and reliability should always be the top priority when purchasing portable ammonia gas detectors. Although you might be inclined to purchase the most expensive, top of the line portable ammonia gas detector; it is worth considering your specific requirements and matching these with the detectors features and benefits. This way you can get the best value for money. The most important thing is to make sure you are buying a reliable product from a reputable manufacturer.
Portable ammonia gas detectors typically use electrochemical sensors. These are compact and generally provide good performance over a wide temperature range. However, electrochemical sensors degrade over time – this is a particular problem with refrigeration applications where the harsh environment can speed up the decline of portable ammonia gas detectors. For this reason, many electrochemical sensors are marketed as disposable gas detectors. Once the sensor degrades past a certain point, the entire detector unit is essentially useless.
However, reusable electrochemical ammonia sensors are available. These are typically called maintainable detectors. These devices have removable sensors and batteries which can be replaced once worn out, effectively giving the unit an unlimited lifespan. This also makes the detector environmentally friendly.
Unless you are carrying out a one-off project, we always advise making sure your portable ammonia gas detectors are maintainable to minimize downtime and reduce long-term upkeep costs.
Ease of Use
For many workers, portable ammonia gas detectors are used every single day. This means it is crucial that your portable ammonia gas detectors are easy to use, with clear displays and alarm functions. This not only reduces the time spent training personnel in their use but helps to ensure that detectors are being used properly and safely. Other considerations for ease of use might include detector weight, and attachments such as belt clips.
