Digital Infrared Thermometer: A Handy Tool for Accurate Readings

All objects emit heat in the from of infrared energy and the best way to determine their temperature is by using a digital infrared thermometer. This is a handy tool that is very easy to use, offers accurate readings and has a practical design. When choosing an infrared thermometer there are several factors to bare in mind including emissivity, the size of the object and the type of surface the you plan to measure. Emissivity basically refers to the ability of a specific surface to emit thermal energy. Most thermometers are designed to measure a variety of emissivity values of different materials including plastic, metal and glass. It is important to mention that the higher the emissivity of the object, the easier it would be to get accurate results about its temperature using a digital infrared thermometer.


The best thing about this practical device is that it allows you to make temperature measurements from a safe distance. This basally means that digital thermometers can identify the temperature of objects without making any physical contact with them. They are ideal for monitoring the temperature of electrical equipment and checking whether there are any extremely hot sports that could cause damage. The non-contact measuring method means that you can use the device to measure moving objects or test applications in vacuum or other controlled atmospheres.

Thermometers can be either portable or fixed-mount. Fixed-mount models are usually used for constant monitoring of the heat emitted by a given application. They are installed at a specific location where they are aimed at one point from the desired distance. Portable models are powered by batteries and are much more convenient. They can easily fit in your pocket or tool bag so you can take them anywhere. Portable or hand-held thermometers include lenses that are designed to focus the generate infrared energy on the detector. The energy is then converted by the detector into electrical signal and presented as units of temperature on the LCD display. This type of thermometer is ideal for maintenance and quality control of electronic equipment and is designed to deliver fast, detailed and accurate results.

To provide optimum accuracy advanced digital thermometers include a built-in laser pointer that serves as a guide particularly when making readings from a larger distance and makes it easier to aim the device towards the desired area on the object or application that is being monitored. The reading shown on the display represent the temperature above, below and around the area pointed by the laser.
