Features
EPA Compliant Measurement: The HI98703 meets and exceeds the requirements of EPA and Standard Methods for turbidity measurements. When the meter is in EPA mode all turbidity readings are rounded accordingly to meet reporting requirements.
Calibration: A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.10, 15.0, 100, and 750 NTU) standards. Calibration points can be modified if user-prepared standards are used.
AMCO AEPA-1 Primary Turbidity Standard: The AMCO AEPA-1 supplied standards are recognized as a primary standard by the USEPA. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density. The standards are reusable and stable with a long shelf life.
GLP Data: The HI98703 features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. Data includes calibration points, date, and time.
Data Logging: Up to 200 measurements can be stored in the internal memory and recalled at any time.
Data Transfer: For further storage or analysis options, logged data can be downloaded to a Windows compatible PC using the RS232 or USB port and the HI92000 software.
Backlit Display: A backlit LCD display provides an easy to understand, user-friendly interface. Displayed codes guide the user step-by-step through routine operation and calibration.
