NBP007 NIR Backscatter Photometer

High-Resolution Analyzer for Suspended Solids and Turbidity Control.

The Kemtrak NBP007 is a fiber optic NIR backscatter photometer designed to precisely measure suspended solids, turbidity, emulsions, dispersions, and foams in real time. With exceptional resolution and no optical density limitations, it outperforms conventional turbidity meters that fail above 1% solids. It is ideal for high concentration applications and enables direct in-line monitoring, leading to greater process control, reduced waste, and improved efficiency.

Key Features

Real-time measurement of 0.001% (10 NTU) up to 100% suspended solids
Dual range: NBP007-L (up to 10% solids) and NBP007-H (10–100% solids)
No signal loss or measurement blind spots at high concentrations
Fiber optic probe with scratch-resistant sapphire window and no moving parts
Automatic cleaning with configurable cycles and durations
Remote zeroing, auto-gain and 16-point calibration tables
Built-in data and event logger with ring buffer
Remote access via HTML/Java WebUI and MODBUS TCP

Applications

Suspended solids and turbidity monitoring
Milk fat and biomass concentration in dairy and biotech industries
Interface detection between liquids or products
Crystallization control in batch processes
Product identification and CIP cycle optimization
Monitoring separator efficiency and detecting valve leakage
Particle size change detection (dual-wavelength feature)
