Features at-a-glance:
Two Measurement Modes – The HI88703 features two options for turbidity measurement: ratio and non-ratio mode. Turbidity measurements can be made in the 0.00 to 4000 NTU (Nephelometric Turbidity Units) when using the ratio mode and in the 0.00 to 40.0 NTU range when non-ratio mode is used.
Multiple Turbidity Units of Measure – Turbidity can be read as Nephelometric Turbidity Units (NTU), European Brewing Convention units (EBC), or Nephelos units.
EPA Compliant – The HI88703 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 – The HI88703 has a powerful calibration function that compensates for lamp aging or changing. The calibration can be done using the supplied calibration solutions or user-prepared standards. A two, three, four, or five-point turbidity calibration can be performed by using the supplied (<0.10, 15.0, 100, 750, and 2000 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 HI88703 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 USB port and the HI92000 software.
Tutorial Mode – The unique tutorial mode provides additional information to help the user during measurements. When enabled, the instrument displays explanations and a confirmation button when a preparation or other operation has to be performed.
Contextual Help – Contextual help is always available through a dedicated HELP button. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.
Backlit Graphic LCD Display – A graphic LCD display provides an easy to understand, user-friendly interface. All messages are in plain text making them easy to read.
