    PRODUCT DESCRIPTION

    The ​​500-04 Type-C​​ represents a pinnacle of engineering in environmental and industrial monitoring technology, engineered to excel in the most demanding scenarios such as mariculture, strongly corrosive wastewater environments, and complex operational settings. As a versatile and rugged sensor solution, it redefines precision and durability by integrating cutting-edge materials, intelligent design, and industry-leading performance—making it an indispensable tool for professionals who demand reliability in harsh conditions.


    Built to withstand corrosion and challenging environments, the sensor features a fluorescent cap constructed from titanium alloy and a body made of gray nylon reinforced with fiber, ensuring superior strength and chemical resistance. Its exceptional repeatability (0.05mg/L for DO) and rapid T90 response time (<40 seconds) ensure responsive, reliable data, even in fluctuating conditions.
