Primary Application: Industrial water treatment process control
The ST-730 series is designed for monitoring the middle range of turbidity in various applications. It is more robust and tolerant to fouling, particulates, and air bubbles compared to other online turbidity meters designed for relatively clean water applications. It also offers better resolution and accuracy compared to high turbidity (suspended solids) meters rated for more than 4000 NTU.
The ST-730 series turbidity probes measure two optical densities and two scattering intensities at two wavelengths. This helps measure a large turbidity range and yet maintain a fine resolution. This design also helps the probe run self-diagnoses.
The small footprint, compact design is similar to an industrial pH probe.
