STRONG Series 2-Color Infrared Pyrometer_CHANGZHOU SIJIE OPTOLELECTRONICS TECHNOLOGY CO., LTD

1. Product introduction

STRONG Series two color infrared pyrometer（also known as ratio infrared pyrometer）, is a series of high performance and intelligent two-color infrared pyrometer. It has solid firm, 304 stainless steel host machine, 304 stainless steel protection jacket with optional air purge and water cooling functions. It uses the manual adjustable focal length, achromatic lens, high reliability circuit design (low temperature drift, full digital measurement design, high integration SOC chip application, visualize OLED operation interface) and software design (ambient temperature compensation, real-time signal processing, abnormal signal processing, software code optimization in all kinds of application environment ).These special designs enable the STRONG series of two-color pyrometers to meet the use in a variety of harsh industrial field and precise temperature control requirements.

STRONG series two-color pyrometer determines the temperature of an object by measuring the ratio of energy at two different wavelengths. The advanced software and hardware design help pyrometers meet the application in harsh environment as moisture, dust, target size change, partial blockage and emissivity change, even if the detection signal attenuates 95%, the temperature measurement results will not be effected.

This series is not only suitable for temperature measurement in general industrial occasions, but also suitable for precise measuring of small targets at long distance, materials with easy changing emissivity, and in occasions with strong attenuation.

STRONG series two-color infrared pyrometer can meet the requirements of two color measuring in various industrial occasions. For example, medium-high temperature below 2000℃, such as: wire rod, hot rolled plate, forging, casting, cement kiln, heat treatment, induction heating, monocrystalline silicon and polycrystalline silicon, etc. It can also be used in ultra-high temperature below 3000℃ measuring, such as vacuum furnace, graphite furnace, high-temperature furnace etc. Measurement has high stability.
