Easy calibration and verification

The Hach 2100Q Portable Turbidimeter provides confidence your measurements are right every time. On-screen assisted calibration and verification saves you time and ensures accuracy.
With an easy-to-follow interface, complicated manuals are not needed to perform routine calibrations. Single-standard RapidCal calibration offers a simplified solution for low level measurements.

Simple data transfer

Data transfer with the 2100Q is simple, flexible, and doesn't require additional software. All data can be transferred to the included USB+Power Module and easily downloaded to your computer with a USB connection, providing superior data integrity and availability.

Accurate for rapidly settling samples

The HACH 2100Q Portable Turbidimeter incorporates an innovative Rapidly Settling Turbidity^TM mode to provide accurate, repeatable 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 in the instrument for easy access and backup. Stored information includes: date and time, operator ID, reading mode, sample ID, sample number, units, calibration time, calibration status, error messages, and the result.

Optical system for precision in the field

The two-detector optical system compensates for color in the sample, light fluctuation, and stray light, enabling analysts to achieve laboratory-grade performance on a wide range of samples, even under difficult site conditions.
