Ratio Measurement Mode – The HI98713 measures turbidity using the ratio method with a 90° and 180° light detector for more accurate measurements. Turbidity measurements can be made in the 0.00 to 1000 FNU range.
Multiple reading modes – Normal measurement, continuous measurement, or signal averaging measurement are reading modes available.
ISO Compliant – The HI98713 meets and exceeds the requirements of ISO 7027 method for turbidity measurements by use of an infrared LED light source.
Calibration – The HI98713 has a powerful calibration function that compensates for variation in light intensity. The calibration can be done using the supplied calibration solutions or user-prepared standards. A two, three, or four-point turbidity calibration can be performed by using the supplied (<0.1, 15, 100 and 750 FNU) 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.
