OLTU600 Online Laser Turbidity Sensor for Circulating Cooling Water

Circulating water typically refers to industrial circulating cooling water. It is widely used in factories to condense steam and cool products or equipment. The OLTU600 online laser turbidity sensor, developed by DOSZ, is a precision instrument designed to measure the turbidity of industrial cooling water. Accurate turbidity monitoring is essential, as poor cooling efficiency can reduce production rates, compromise product quality, and even lead to costly accidents.?

?

According to industry standards, the turbidity of water in open indirect cooling systems should generally be ≤20 NTU. For systems using advanced heat exchangers such as plate-type or spiral-type models, turbidity requirements are stricter, ≤10 NTU. The OLTU600 offers a wide measuring range of 0.001~100 NTU and automatic range switching, ensuring precise and reliable measurements for diverse industrial needs.?
