Features
- Single Beam Design: The HI93703 measures turbidity using a light detector at 90° for detection of scattered light. Turbidity measurements can be made in the 0.00 to 1000 FTU range.
- ISO Compliant: The HI93703 meets and exceeds the requirements of ISO 7027 method for turbidity measurements by use of an infrared LED light source. As this meter has been designed to follow this ISO method, the units are displayed in FTU (Formazine Turbidity Unit); FTU is equivalent to the other internationally recognized unit of NTU (Nephelometric Turbidity Unit).
- Calibration: The HI93703 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 or three-point turbidity calibration can be performed by using the supplied (0, 10, and 500 FTU) standards.
- 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.
- Last Calibration Date: The HI93703 allows the user to store the last calibration date. Recall of the last calibration date is simple with a press of the “DATE” button on the face of the meter.
- Low Battery Indicator: A “LO BAT” indication will appear on the lower right corner of the display when the batteries are low and need to be replaced. At this point, the instrument can still perform approximately 50 measurements. When the battery is too low to perform reliable measurements, a message appears and the meter will automatically switch off.
