Technical Description

The OBS300 uses its downward-facing optics to emit a nearinfrared light into the water. It then measures the light that bounces back from the water's suspended particles.

If an obstruction is in the emitted light's range, the light will scatter back and the turbidity reading will be too high. This probe's downward-facing optics avoid obstructions around the sides of the probe. The OBS-3+ is available for locations that have obstructions above and below the probe.
