La OBS-3+ es una sonda sumergible con ópticas laterales para medir la turbidez . Utiliza la tecnología OBS® para medir los sólidos en suspensión y turbidez, en aplicaciones que van desde monitorización de la calidad de agua en ríos y riachuelos hasta el transporte de sedimentos y dragados. Los dataloggers Campbell Scientific miden la salida de la sonda y calculan la turbidez.
Leer másThe OBS-3+ uses its sideways-facing optics to emit a near-infrared 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 sideways-facing optics avoids obstructions above and below the probe. The OBS300 is available for locations that have obstructions around the sides of the probe.
