Hach 2100QUSB Instrument Kit Includes the Below Components in Addition to the Standard Components of the Hach 2100Q:

• USB+Power module
• Module cover 
• Connector cover 
• Universal power supply w/ plug adapters (North America, EU, UK, Australia) 
• Standard USB cable with Mini USB connector (allows connection to PC) 
• Special USB cable adapter (allows connection to Citizen PD-24 printer) 
• Manual

• 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
  Data transfer with the optional USB+Power Module is simple, flexible, and doesn't require additional software. All data can be transferred to the module in XML format and easily downloaded to your computer with a USB connection, providing superior data integrity and availability.
• Accurate for rapidly settling samples
  The innovative Rapidly Settling TurbidityTM 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 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.

On-Screen Assisted Calibration and Verification
The 2100Q gives you confidence that your results are accurate, without having to read long manuals for calibration and verification instructions.  All the core measurement information is on a single screen.

Rapidly Settling Turbidity ™ (RST) Mode

Hach has developed an innovative solution to alleviate the uncertainty caused by changing turbidity readings in samples that quickly settle. The 2100Q’s RST reading mode uses an exclusive algorithm that reverse calculates and continuously updates a calculated value of turbidity to a point in time when the sample begins to settle out of solution based upon the accumulated trend of the measured values. This results in values that are more accurate and repeatable than those obtained using traditional smoothing techniques, such as averaging.

Although the sample continuously settles out of solution, the RST calculated value does not change. No more guessing and no more replicate runs:  you get the right answer every time.
