An infrared thermometer is a device used for temperature measurement. The infrared thermometer (temperature measuring gun) uses a non-contact temperature measurement method to accurately measure the surface temperature of the object. Infrared temperature measurement has the characteristics of high precision, fast response, and high safety factor. It is suitable for many scenarios such as preventive maintenance of electrical equipment, quality management of production lines, and food hygiene and safety. The following is the ATO infrared thermometers price list.

In the steel production process, monitoring the temperature is essential to improve productivity and product quality. Whether the temperature of the production process is within the range required by the process; whether the temperature of the heating furnace is too low or too high; whether the rolling mill needs to be adjusted, or to what extent it needs to be cooled, infrared thermometers can solve these problems well. Infrared thermometers are mainly used in continuous casting, hot blast furnace, hot rolling, cold rolling, bar and wire rolling in the steel processing and manufacturing process.

Understanding the infrared thermometers’ working principle, technical specifications, working conditions, operation and maintenance is the basis for users to correctly select an infrared thermometer or use it. An infrared thermometer consists of optical system, photoelectric detector, signal amplifier, signal processing and display output. The optical system of infrared thermometer accumulates the target infrared energy in its field of view. And the size of field of view is determined by the optical components and location of the thermometer. The infrared energy is focused on the photoelectric detector and converted to corresponding electrical signal. The signal is corrected by the amplifier and signal processing circuit according to the algorithm inside the instrument and the target emissivity and then is converted to the temperature value of measured target.

Infrared temperature measurement technology plays an important role in production, product quality control and monitoring, on-line fault diagnosis and safety protection, as well as energy saving. Compared with the contact-type temperature measurement method, infrared temperature measurement has the advantages of fast response time, non-contact, safe use and long service life. Non-contact infrared thermometer involves three major series of portable, on-line and scanning thermometer, with various accessories and computer software. Moreover, each series has different types and specifications. Among these thermometers with various specifications, it is very important for users to choose a correct type of infrared thermometer.

How to choose a right infrared thermometer? The first thing to think about is performance indicators, such as temperature range, spot size, working wavelength, measurement accuracy, response time, etc. Environmental and working conditions are also taken into account, such as ambient temperature, window, display and output, protection accessories, etc. Other factors, including convenience, maintenance and calibration performance and price, etc., also affect the selection of the infrared thermometer.

The infrared thermometer is used for measuring the surface temperature of the object. ATO infrared thermometer is non-contact, handheld and easy to operate, especially suitable for measuring the temperature of various hot, hazardous or hard-to-reach objects. This infrared thermometer consists of Optics, temperature sensors, signal amplifier, processing circuit and LCD display. The Optics collects the infrared energy emitted by the object and focus it to the sensor. Then the sensor transforms the energy into an electricity signal. The signal will be turned into a digital number shown on the LCD after the signal amplifier and processing circuit.

Angle of measurement

In order to ensure accurate measurement, keep the infrared thermometer following the surface normal direction of the measured object as possible in measurement (perpendicular to the target surface). If you fail to guarantee the instrument in the normal direction, it is supposed to measure in 45 degree angles with the normal direction, otherwise the displayed value of the infrared thermometer will be low.
