The HACH 2100Q Portable Turbidimeter provides confidence your measurements are right every time.

• Single-standard RapidCal™ calibration offers the simplest solution for low-level measurements.
• Single-step verification and on-screen assisted calibration eliminates the need to reference complicated manuals.
• Exclusive algorithm in the Rapidly Settling Turbidity™ mode provides accurate, repeatable measurements for rapidly settling, difficult-to- measure samples while eliminating the need for redundant measurements and estimating.
• 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.
• 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.
