Before purchasing any medical equipment (either online or in a showroom), you should always seek the advice of your doctor. Ask them to confirm exactly what you need to buy and what features the product should have. In fact, some teams require that you have a prescription to buy it, similar to how you will need a prescription to obtain certain medications. It may also be worth contacting your insurance provider to make sure they will provide you with compensation for the cost of the machine. They will generally only reimburse customers who have purchased equipment on the advice of a registered doctor, so this will provide you with an additional burden to consult with your doctor. Your doctor should even be able to give you good advice on where to buy the equipment or give you the names of some reputable providers.
If you are a regular Internet user, you may want to consider joining a forum for people who have the same medical conditions as you, so that you can discuss your ideas and experiences with others who are in the same position. They may be able to help you choose the best equipment from the most reputable supplier and avoid any low-quality temperature screener.
There are a large number of equipment suppliers online and you may be able to find lower priced items on the internet, however you should choose your supplier carefully and not make judgments based solely on price. Make sure that your chosen supplier has a good "after sales" package, which includes the complete installation, a tutorial on the use and maintenance of the machine and periodic services. It is especially important to consider what services the provider offers in the event of a problem with the equipment, because this equipment can be a lifesaver for the user, and the problems can cause potential health risks. There are specialized providers of orthopedic equipment, palliative solutions, and equipment for use by the elderly, as well as many other types of specialists, so try to choose a suitable provider. You can even buy some second-hand equipment.

While some home equipment suppliers store only the equipment itself, some suppliers will also have a full range of medical supplies, such as syringes, latex gloves, and medications. If you plan to pay for your equipment with your health insurance, be very careful, because some insurance coverage providers do not classify expendable medical items like these as home medical equipment, and they may not be covered under the terms of your policy at all.
