A digital thermometer is a very common utensil in any ice cream parlor. But do you really know how they work and what exactly they are used for? Although the answer may seem very obvious, you need to know that there are different types of digital thermometers. In the world of ice cream, each one fulfills a specific function, which is usually very important in certain artisanal and industrial ice cream production processes.
Digital thermometers have integrated transducers, these are small devices that transform the manifestation of an input energy into an output one, but with very similar values. So they have a small panel with electrical circuits that convert the recorded variations in a final figure through its digital display.
Characteristics of digital thermometers
- They have a small LCD screen that displays the perceived temperature data.
- They are mobile devices, very compact and easy to carry.
- They are usually powered by removable batteries.
- They offer the possibility of choosing the scale on which we want to measure the temperature.
- The results are obtained in a short period of time and are easy to read compared to traditional thermometers.
Advantages of using digital thermometers
- Their sensors accurately capture the results of the temperature we want to record.
- They work quickly and easily, in a matter of seconds it is possible to know the results.
- Some models allow to store a record of temperatures obtained.
- Its use allows to check that our ingredients, mix and ice cream have the correct temperature. As well as detecting faults in the mix or in the storage and refrigeration equipment.
- They have a compact design, so they do not take up much space.
- No training is required to learn how to use them. They are easy to operate and just by reading their instructions you will understand how to use them.
- The prices of digital thermometers are generally low, offering excellent value for money.
Infrared Digital Thermometers

The infrared thermometer is a digital tool that allows us to take the temperature of the objects we want without coming into direct contact with them. So it is ideal for recording the temperature of moving machinery, rollers or even in conditions where distance is required, or in places that are not completely safe.
Infrared digital thermometers work thanks to its special lens that allows to focus the infrared energy rays in a pyrometer, to convert it into an electrical signal, which is possible to measure in temperature units, after being compensated with the ambient temperature. It is precisely this feature that makes it possible to record the temperature of the object quickly and easily, without coming into contact with it.
Aspects to consider when buying a digital infrared thermometer
There are many digital thermometers for sale, but before looking for Amazon digital thermometers or Walmart digital thermometers, it is important that you study the conditions of your premises and the needs of the production processes of your ice cream parlor:
- Field of view: this will depend on the size of the lens and the distance with which you need to measure the temperature, which is determined by the optics that the pyrometer handles.
- The surface: evaluating the type of surface on which you will take the temperature is also an aspect to consider when purchasing your thermometer. Since this will determine the emissivity conditions, i.e. the ratio of the energy radiated by the object at a certain temperature to the energy of a black body, also known as a perfect radiator, which is usually 1.0.
- Spectral response: generally, infrared thermometers work with a spectral response of approximately 8-20 µm. One of the ranges least affected by the effects of oxygen and water in the atmosphere. This will directly influence the accuracy of the temperature recording.
- Mounting range: according to the conditions in which you will work, it is necessary to take into account the mounting range, whether you will use infrared guns or fixed sensors.
- Response time: this way you will know how long it will take to receive the temperature recording information.
Digital Pocket Kitchen Ice Cream Thermometer

In the world of ice cream, digital thermometers or pocket thermometers are very functional to take the temperature of liquids such as ice cream mixes, as well as the temperature of certain ingredients to prepare our ice cream and also the temperature of the final product. If you want to prepare an ice cream with a creamy texture and quality, the temperature at which you work will be essential to achieve it, and for this, it is necessary to have one of these thermometers at hand. Usually, the digital pen thermometer has inside a kind of probe made of stainless steel, which is responsible for recording the temperature of the objects. It works very simply, does not take up much space and digital thermometers are usually quite affordable.
Advantages of the pocket digital kitchen thermometer
- Allows almost instantaneous measurement of the internal temperature of any solid food.
- They have a discreet and compact design that does not take up much space in the kitchen.
- They offer highly accurate readings.
- They have a small built-in LED display that makes it easy to read the data.
- They are powered by removable batteries and some models have an auto shut-off function to save energy consumption.
- Their use allows us to identify the temperature of the ice cream stored in the display case or counter, to ensure that they are in good condition for sale to the public.
Digital Data Logger Thermometer

It is a digital thermometer of greater complexity, with a larger memory, which allows it to record the temperature gradually, in order to store the data obtained and provide a balance of the information collected during the period of time that has been configured. For ice cream stores, it is very useful to systematically record the temperature and humidity values of the chambers in which the ice cream is stored. This allows the creation of a history that can be downloaded to a PC or computer, which is very helpful for the development of the Hazard Analysis and Critical Control Point plan.
Advantages of the digital temperature recorder thermometer
- It performs measurements with high accuracy.
- It has an integrated memory that allows storing the data record of the temperatures taken in a period of time.
- The batteries of these types of thermometers are usually very durable.
- They can be connected to computers to download the information obtained.
- They provide important information to improve the production and refrigeration stages of the final product.
