Digital thermometers

Are an important part of any household. From medical thermometers to fridge/freezers, they have a number of uses in the home.

However, they are also used in a number of other places like cars, hospitals and nursing homes to the less obvious places like server rooms and airplanes. Digital thermometers offer the easiest way to check the temperature of any given object or of the current temperature.

For most of us, when a thermometer is mentioned, a picture of a long tube with red liquid comes into mind. This is because the clinical thermometer is one of the most common thermometers that we, as adults, would have come across. While it an iconic form of thermometer, now there are much more advanced solutions like analogue and digital thermometers that perform the same tasks in slightly different manners to produce results that are more accurate.

While analogue thermometers make use of mercury to push the dials in a clock like design to give the reading of temperature, digital thermometers utilise specially engineered electronic heat sensors that can measure heat accurately.

How do digital thermometers work?

The average digital thermometer had special materials that can change their resistance value to even the slightest amount of change in heat. These materials, called thermo resistors, are used in conjunction with certain sensors, which collect the resistance values. They are then passed on to a low powered CPU that interprets the data and displays it as temperature.

Some advanced thermometers make use of infrared to measure temperature, as well as find the temperature of different regions.
Coupled with an infrared display camera, these thermometers are used by fire fighters to find the source of heat in areas, which may be partially covered by smoke or have low lighting.

Benefits of a digital thermometer

At this moment in time, digital thermometers offer general users the quickest and most accurate reading, which makes them ideal when you are looking for both responsiveness and precision.

The technology used in them means that they are extremely sensitive to temperature changes and can detect even the slightest of drops or increases. This makes them ideal for measuring temperatures in critical electrical components, checking room temperatures, checking exact body temperatures, etc.

Digital thermometers also can be programmed to give an electrical output at a certain temperature, making them efficient for stopping critical components of any machine from overheating. This ability to modify the thermometer can be used for home purposes like alerting when the bath water for the baby reaches a certain temperature, or if the inside of the oven is overheating.
While responsive and accurate, the downside of digital thermometers is that some of them may not be suitable for endurance or high-intensity heat, although the manufacturers have discovered ways to make the heat sensors more durable and more receptive to higher temperatures in recent years.

Types of digital thermometers

Depending on their use, there are various types of digital thermometers available in our range. From body temperature recorders and bath thermometers, to oven and meat thermometers, we have a wide range from which you can choose.

It is essential to use a type of thermometer only for its specified purpose as usually they are optimised for that and chances are alternative uses may lead to inaccurate readings or in some circumstances, danger.

It is imperative that you ensure your thermometer can handle the reading that you are going to be subjecting it to regardless of its use. For instance, using a meat thermometer on other foods may seem fine, but with a range from 170 - 270 degrees, other foodstuffs like confectionery syrup can reach temperatures as high as 350-400 degrees, which will most likely break the thermometer. Therefore, always check on our description page when shopping in our digital thermometer range from our website for the exact purposes and temperature range of the particular digital thermometer.

Using a digital thermometer

Before you start using a digital thermometer, make sure you clean its input area thoroughly. It does not matter if you had cleaned it before storing it, make sure you do it again before use with an antibacterial solution it if it is going to be used on a human body or a pet.

On the other hand, if it is going to be used for some other purpose, you can always clean it with a bit of soap and rinse the area thoroughly, although be careful not to spill water on the display or the electrical part of the thermometer as it may damage it unless it is a waterproof digital thermometer.

Next, check if the reading is zero when the thermometer is switched on. It should change to room temperature after a moment. Let it stay open for another few seconds while it gets more consistent and stable in the readings. After that, take your reading.

The reading process depends on the model of the digital thermometer you use. Some take a few seconds while others may take a minute. Once displayed, wait a minute to verify the reading. Finally clean the input area again after switching the thermometer off and store it away in a dry place.

I have purchased five of these over the years ….. One for me and because I find it so useful, four for relatives and friends as Christmas presents. Clearly I think both the thermometer and customer service from this company, really good

Ordered this Thermometer to replace my previous one which I lost. (a gift to Neptune?). To take the sea temp when I swim. So far so good! and the scale is easier to read whilst treading water.
