HU-200TB-H

Field-installation type turbidity meter

For low turbidity management of filtered water, such as in distribution reservoirs.

Ideal for low turbidity management of filtered water in applications such as reservoirs. By employing the transmitted scattered light method and an electric wiper cleaning function, stable measurements are achieved.

Stable measurement

The transmittance/scattering light method cancels out variations in light source, detector, and attenuation of light due to contamination.  Additionally, featuring an electric wiper cleaning function (optional) that provides an overwhelming cleaning capacity.

High-brightness LED light source in use

Capable of measurements with a minimum resolution of 0.001 degrees.

Automatic range switching

Supporting four ranges.

Convenient optional feature

An optional pressurized de-aerating tank is available.
