HU-200TB-IM
Immersion-Type Turbidity & Suspended Solids Analyzer
The HU-200TB-IM is an immersion-ready turbidity and suspended solids sensor designed for direct installation in intake water, wastewater, or treatment tanks. It offers selectable measurement modes—either 90° scattering or transmission—for flexible monitoring and includes a robust auto-cleaning wiper and durable LED optics for stable, long-term field performance.
Why Choose HU-200TB-IM
Flexible Measurement Modes – Choose between 90° scattering or transmission techniques depending on sample characteristics.
-
Extended Range – Measures up to 4,000 NTU for turbidity and up to 2,000 mg/L for suspended solids.
-
Durable, Low-Maintenance Design – Built with a resilient LED light source, PFA sensor head, and auto-wiper for reliable operation.
-
Immersion Flexibility – Mounts directly into tanks or water columns for real-time, in-situ monitoring.
