Pyrometers - application, types, design

Pyrometers are infrared thermometers that allow you to measure the temperature of any body or environment in a non-contact manner. These devices have a wide range of uses - they help to search for hot and cold spots at objects, measure temperatures in hazardous environments and hard-to-reach places, and control technological processes. On sale you can find pyrometers for personal and professional use, varying in options and cost. The most modern models allow you to display the obtained data on a computer for analysis and generalization. In this rating, only the best, functional and high-quality pyrometers are offered to your attention.

How to choose the right pyrometer

The choice of device depends primarily on where and for what purposes it will be used. Some models are better for measuring body temperature, while others are designed for culinary purposes.

Which pyrometer to choose for your home

The most popular in home use are portable infrared devices. A stationary device operating from the network is unlikely to be useful for domestic purposes, despite its high accuracy. When choosing a pyrometer for your home, you need to consider:

• temperature range, in everyday life there will be a sufficient range from - 50 to 380 ° C;
• accuracy, the error of the device should be no more than 3 degrees;
• range - pyrometers can be contact or non-contact; when using the latter, you need to take into account the optical resolution, or the required distance to the object;
• speed, in everyday life it is convenient to use devices with a response from 0.1 to 0.15 seconds.

Also, when comparing pyrometers and choosing the best one, you can take into account additional parameters. Some models can measure humidity. It is useful if the device is able to save the results of tests performed in the built-in memory.

Which pyrometer is better to choose for a pastry chef?

When choosing a pyrometer for baking in a workshop or at home, you can buy a non-contact device with a range from - 50 to + 400 °C. But models with a thermocouple perform best in cooking; they are connected to the main unit and measurements are taken using the contact method to obtain the most accurate results. Then the test is repeated remotely to compare the indicators; the difference usually reaches several degrees.

In cooking, contact pyrometers with a thermocouple remain the best

How to choose a medical pyrometer

Medical devices are often used instead of conventional thermometers. You need to select a device according to the following parameters:

• contact or non-contact action, devices of the first type are more accurate, although the second can be used for several people without disinfection;
• accuracy, for a medical pyrometer the minimum error is important;
• functionality, it is useful if the device is equipped with a sound signal and can indicate the completion of the measurement.

Important! The medical device does not require a large temperature range.

How to choose a non-contact infrared pyrometer

The best pyrometers for measuring temperature using a non-contact method are very popular in everyday life. Such devices demonstrate high accuracy and are versatile. They can also measure very hot, dangerous or hard-to-reach objects.

When choosing, you need to look at several characteristics:

1. Range. If you only need to determine body temperature and weak thermal radiation from surfaces, you can choose a device with small values. For culinary use, you need to buy a model with a wide range, and it is desirable that even very high temperatures are kept away from the maximum possible readings of the device.
2. Spectral sensitivity. It is better to choose a device that operates on short waves; it is suitable for most household measurements.
3. Chroma. Usually, single-color pyrometers are sufficient for home use. Two-color models should be chosen if you need to evaluate the temperature of very small and hot objects, as well as objects whose radiation is partially blocked by any contamination or obstacles.

When choosing a home pyrometer, first of all, you need to evaluate its thermal range

Infrared devices equipped with a laser sight are considered the best. They help measure the temperature of an object at a specific selected point and thus reduce the likely error.

How to choose a pyrometer for measuring temperature

If the device is to be used instead of a thermometer, first of all you need to decide on its type - contact or non-contact. Devices from the last category are recommended for young children. But for adults and teenagers it is better to use contact pyrometers - frontal or ear. They give more accurate readings and are almost as good as mercury thermometers.
