High Accuracy Turbidity Measurement

The 2100Q Portable Turbidimeter offers a unique combination of advanced features, such as easy calibration and simplified data transfer, and measurement innovation for rapidity settling samples, giving you confidence you're getting accurate results every time.

Easy On-Screen Assisted Calibration and Verification

Save time and get accurate results with an easy-to-follow interface that eliminates the need for complicated manuals to perform routine calibrations. Single-standard RapidCal™ calibration offers a simplified solution for low level measurements, while ensuring you meet reporting requirements.

Simple Data Transfer
Customizable power and connectivity modules enable smooth data transfer and flexibility. Optional USB + Power module allows data downloads to any computer via USB port.

Accuracy for Rapidity Settling Samples
The innovative Rapidly Settling Turbidity™ mode provides accurate measurements for difficult to measure, rapidly settling samples. An exclusive algorithm that calculates turbidity based on a series of automatic readings eliminates redundant measurements and estimating.

Convenient Data Logging
Up to 500 measurements are automatically stored for easy access and backup, including: date and time, operator ID, reading mode, sample ID, sample number, units, calibration time, calibration status, error messages and the result.
