HJ3 Composite Technologies Honored as National Finalist in Cleantech Open Accelerator Tucson, AZ — HJ3 Composite Technologies, LLC, based in Tucson, Arizona, has been named a national finalist in the 2024 Cleantech Open Accelerator. This achievement follows their recent victory at the Rocky Mountain Region qualifier, marking another milestone in the company's journey toward sustainable innovation. The Cleantech Open, now in its fifth year, is a global initiative that has helped bring over 727 clean technology startups to life, supported alumni companies in securing more than $800 million in external funding, and played a key role in creating thousands of green jobs since 2006. As a national finalist, HJ3 will receive $20,000 in cash and in-kind support, and will compete against 24 other regional winners from across the U.S. at the Cleantech National Global Forum on November 20th and 21st in San Jose, CA. There, they'll have the chance to connect with top investors and vie for prizes worth up to $250,000, further boosting their growth and impact. Specializing in advanced composite systems, HJ3 is committed to providing sustainable solutions for reinforcing aging infrastructure worldwide. Their patented carbon fiber composites offer superior strength, lightweight performance, and resistance to corrosion, chemicals, abrasion, extreme temperatures, and fire. With over 10,000 successful applications globally, HJ3 helps infrastructure owners reduce costs and environmental impact while extending the lifespan of structures by up to 30 years. The construction industry generates massive amounts of waste and carbon emissions each year. In the U.S., around 140 million tons of steel and concrete end up in landfills annually, with replacement projects contributing billions of tons of CO2. HJ3’s eco-friendly alternatives help cut down on both waste and emissions, offering government agencies and Fortune 500 companies savings of 60% to 90% on repairs or replacements. The Cleantech Open is the world’s largest cleantech accelerator, dedicated to discovering, funding, and supporting entrepreneurs tackling critical energy, environmental, and economic challenges. As a 501(c)(3) nonprofit, it provides the resources, expertise, and partnerships needed to turn bold ideas into thriving global businesses. With over 1,500 volunteers and sponsors worldwide, the organization bridges public and private sectors to drive the growth of the clean technology economy. Low-temperature 2-color Ratio Pyrometer
This classification includes two color infrared pyrometers measuring range is 250℃-2200℃.
Compared with one color infrared pyroemter, two color pyrometer measuring result will not change with state of object surface (surface roughness or surface chemical state), that means two color infrared thermometer accuracy will not be affacted, while the 1-color pyrometer will.
Products in this classification are usually applied to metallurgical industry(rod and wire mills, Hot rolling mills), foundry, cement kiln, induction heating, heat treatment, heating furnace, vacuum furnace, monocrystalline silicon, polysilicon, semiconductor and other industrial temperature measurement.

The optical part of pyrometer, such as glass, will accumulate some dust in the surfac after using for a period. Water, gas, oil vapour, dust in the air will reduce the emissivity coefficient, so the monochromatic pyrometer will reduce the measured value at this time. The Dual color pyrometer measures the ratio of infrared radiation intensities of two band wavelength in a specific range. With dust, water vapor and other disturbances, the signals of two wavelength fall simultaneously and the ratio remains constant after division. And user just need to wipe the glass when it is too dirty.
Monochromatic thermometers cannot measure objects smaller than the field of view. When the object does not fill the field of view, the measurement temperature will be low. A bicolor pyrometer can measure objects smaller than the field of view.
