Logger version super wide range turbidity sensor with wiper INFINITY-Turbi ATU75W2-USB

■Description
Infinity-Turbi is an autonomously deployable data logger for long-term turbidity measurements. With dual sensors for low (0 to 1,000 FTU) and high (0 to 100,000 ppm) ranges, the instrument can provide Highly accurate turbidity measurements in normal to muddy water. Infinity-Turbi has a mechanical wiper to keep the optical window clean, making long-term observations possible. The instrument has temperature and depth sensors as standard as well, and matches various measuring situations and applications.
