The radiation thermometers are referred to as the duct temperature sensor which measure the object temperature by electromagnetic radiations using Planck law. It usually consists of the optical lens which collects this radiation over the detector. The signal received by the detector can be measured by converting them into the electronic system of temperature reading which later is displayed over the digital screen.
The IR thermometer provides you with convenient and fast temperature readings without coming in direct contact with the object or the subject. The only thing that you need to do is, press the trigger and have the reading over the LCD display. It is a reliable gadget to measure temperature of hazardous, hot or hard to reach surfaces without putting much effort. This digital measuring unit provides you with numerous temperatures reading instantly.
The invisible infrared energy is usually transferred from the object or the subject in three ways that is: reflection, transmission and emission. In this process the emitted energy is used to measure the precise surface temperature of the object or subject.
However there are few factors which affect the accuracy of temperature reading of the object or the subject such as:
Field of view: Ensure that the target of the object should be larger than the spot size of the measuring unit. The target must be two times larger than the spot size for measuring the accurate temperature.
Distance spot ratio: Optical resolution of the object is referred to the distance ratio of the object particularly from the measuring instrument which is compared with the size of the spot of the object to be measured. The large number of ratio related to distance and spot size results into better resolution of the instrument.
This instrument is widely used in several manufacturing areas such as glass, cement, semiconductors, ceramics, metals, paper, coatings, textiles, plastics, etc. Furthermore it helps in boosting the productivity of the automation and feedback control related to product quality. It helps in checking temperature related to numerous safety equipments such as rescues or fire-fighting.
This measuring may also help in detecting the hot spots or leaks and precise temperature of products like freezers, HVAC equipment, compressor motors, refrigeration lines, walk-in coolers, ovens, rotisseries, deep fryers, dishwashers and ranges.
The most reliable example under this kind of measuring tool is of MCROTEMP MT100 Non-Contact Thermometer. This offers the temperature range from 27 to +230 degrees F and has a distance spot ratio of 1:1. This compact size gadget is a versatile tool for technicians which may carry it easily in their pocket or tool-kit easily. It is an affordable, durable, portable and user-friendly gadget that can be used to measure the hot and cold spots of almost any movable or immovable object with great ease and comfort.
However there is one drawback concerning this product that is it works miraculously to measure the temperature of the object under 235 degrees F or quite more. But it completely becomes inactive for measuring temperature of the object which has the temperature ranging above 400 degrees.
Therefore while buying this innovative tool make sure to keep this point into consideration so that later on it may not cause any inconvenience to you.
