Fresnel lens thermometers are mostly used within the meals business! They’re what you’ll use to measure the temperature of that Christmas turkey or (greater than probably) closely utilized in a restaurant setting.

Being in a restaurant, they should supply accuracy, mixed with ruggedness, as they could be dropped and might’t be inclined to break. The producers of Fresnel lens infrared thermometers tackled this drawback by making certain that every one of their Fresnel lens thermometers had been encased in a tough plastic – this made them more durable and tougher to interrupt when dropped.

How Do Fresnel Lenses Work? 

Fresnel lenses had been initially designed to be used in lighthouses. The best way that Fresnel lenses work is by altering the route of sunshine utilizing a collection of glass prisms, set contained in the lens of the infrared thermometer. These prisms focus the beams of infrared mild to permit for the thermometer to make a precision studying from as far-off as twelve inches.

This permits for Fresnel lenses for use in various kinds of environments and nonetheless present correct readings.

What Are Some Benefits of Fresnel Lens Thermometers?

 A few of the benefits of Fresnel lens infrared thermometers are as follows:

  • Plastic encasing makes them much less inclined to breakage when dropped.
  • Cheaper than their Mica lens counterparts, whereas not sacrificing a big quantity of efficiency or options.
  • Equally to Mica lens infrared thermometers, Fresnel lens thermometers are in a position to take correct temperature readings from 6”-12” away.

Fresnel lens infrared thermometers have a tendency to offer much more correct readings than their no-lens counterparts and due to their capability to function at distances of a foot away, present much more versatility than their no-lens counterparts.

One of many key advantages of utilizing a Fresnel lens thermometer is that you simply don’t sacrifice versatility while you purchase one – a Fresnel lens thermometer isn’t used within the sorts of cases {that a} Mica lens thermometer can be – and due to this fact doesn’t have the temperature vary capabilities of the Mica – however it doesn’t want it.

While you purchase a Fresnel lens, you’re shopping for the rugged construction of the plastic that it’s constructed into – you possibly can drop the thermometer with out breaking it.

How Fresnel Lenses React to Change in Temperature

 Much like Mica lenses, Fresnel lenses react to modifications in temperature – taking a while to regulate to the change in ambient temperature. If you happen to’re taking your Fresnel lens infrared thermometer from room temperature to a freezer, for instance, you’re going to wish to let the thermometer relaxation in that setting for about 20 minutes. In any other case, the thermometer will throw up an error studying.

Letting it relaxation within the setting for 20 minutes, will give it time to acclimate and also you’ll have the ability to use it correctly once more.

It doesn’t matter what your want for an infrared thermometer is – whether or not you want it to measure water temperature, or physique temperature, the Fresnel lens is bound to give you the accuracy you want, from the space you want, each time. You’ll want to inventory your Fresnel lens infrared thermometers – although fortunately, they’re constructed powerful, so that you received’t want to switch them in the event that they’re dropped!
