Improving reliability in low concentration areas! Energy-saving design with a safe waterproof structure!

The TB-31 is a portable turbidity meter that enables easy turbidity measurement in the field using an immersion-type sensor. It is ideal for measuring turbidity in general environmental water such as rivers and lakes, as well as in factory and construction wastewater. The repeatability in the low measurement range has significantly improved reliability to ±0.5 NTU compared to our conventional products.
