Anderson-Negele ITM-4 | 4-Beam-Turbidity Meter

The ITM-4 measures low turbidities from 0 to 5,000 NTU (0–1,250 EBC). It is ideal for filter monitoring and phase separation of clear media. Four beams of 860 nm alternating light give colour-independent readings, and the glass-free sapphire optics compensate for window fouling. It is a compact unit with no separate evaluation box.
