Electric heating tube talk about infrared thermometer infrared thermometer performance
Infrared thermometer is through the reception of the target object emission, reflection and conduction of energy to measure its surface temperature. The detection element within the pyrometer delivers the collected energy information to a microprocessor for processing and then converts it into a temperature reading for display. In models with a laser sight, the laser sight is used for aiming purposes only. Its performance is described in Table 1.PT, TI series of portable thermometers developed by Beijing Infrared Times Temperature measurement range -20 ℃ - 400 ℃ Display resolution 0.1 ℃ (<199.1 ℃ when )

Table 1 Infrared Thermometer Performance In order to obtain a temperature reading, the distance between the thermometer and the test target must be within a suitable range, the so-called "spot size" (spot size) is the area of the thermometer's measurement point. The further away you are from the target, the larger the spot size will be. The ratio of distance to spot size, or D:S, is used.
(1) Aspects of performance indicators, such as temperature range, spot size, operating wavelength, measurement accuracy, window, display and output, response time, protection accessories, etc.; and
(2) Environmental and working conditions, such as ambient temperature, window, display and output, protection accessories, etc.; and
(3) other selection aspects, such as ease of use, maintenance and calibration performance and price, etc., also have a certain impact on the choice of pyrometer.
With the technology and continuous development, infrared thermometer best design and new advances for users to provide a variety of functions and multi-purpose instruments, expanding the choice. Other aspects of choice, such as ease of use, maintenance and calibration performance and price. In the selection of pyrometer models should first determine the measurement requirements, such as the measured target temperature, the measured target size, measurement distance, the measured target material, the target environment, response speed, measurement accuracy, with portable or online and so on; in the existing various models of pyrometer comparison, selected to meet the above requirements of the instrument model; in the many models that can meet the above requirements to choose out in the performance, features and price of the * best match.
