The Pressure Resistant Reflex Water Boiler Gauge Glass (AT17) is a high-performance liquid level monitoring solution tailored for boilers, pipes, and pressure vessels. Made from premium borosilicate glass, this reflex gauge glass features a 17mm thickness and multiple size options (340×34×17mm to 115×34×17mm), ensuring compatibility with diverse industrial equipment. It is also known as sight glass and reflex glasses, providing real-time observation of water and liquid level changes in high-pressure and high-temperature environments.
Exceptional Pressure & Temperature Resistance: Withstands 520℃ temperature shock and low thermal expansion coefficient (3.3×10⁻⁶/K), 1/3 of ordinary glass.
Eco-Friendly & Safe: Uses arsenic-free clarifiers, complying with food safety standards such as GB 4806.5-2016 for food contact materials.
High Transparency: Transmittance exceeds 92%, minimizing light scattering and ensuring clear liquid level display.
Multiple Size Options: Available in 9 standard sizes, suitable for different boiler and pressure vessel configurations.
Its made from Borosilicate, it is used in lever gauge in boiler for water position.
