Portable ISO Compliant Turbidity Meter with Data Logging and PC Connectivity
HI93703-11
Description
The HI93703-11 is a high accuracy benchtop turbidity meter used to determine the turbidity of water and wastewater with high precision in the field as well as in the laboratory. The meter is supplied complete with AMCO-AEPA-1 primary turbidity standards used for calibration and performance verification. The HI93703-11 meets and exceeds the requirements of the ISO 7027 Method for turbidimetric measurements. Additionally this meter contains a real-time clock and the capabilities to log measurements and transfer them to a PC using the HI92000 software.
• Auto shut-off
• Logging and real time clock
• Positive-locking cuvette system ensures cuvette is firmly placed in the cell
The HI93703-11 Portable ISO Compliant Turbidity Meter with Data Logging and PC Connectivity is specially designed for water quality measurements, providing reliable and accurate readings, even within low turbidity ranges. The instrument is based on a state-of-the-art optical system which guarantees accurate results, assures long term stability, and minimizes stray light and color interferences. Periodic calibration with the HI93703-0, -05, and -10 standards compensates for any variations in intensity of the LED light source. The 25 mm round cuvettes composed of special optical glass guarantee the repeatability of turbidity measurements. HI 93703-11 also includes a real-time clock and log-on-demand capability.
Features/Benefits:
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.
Calibration
• The HI93703-11 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.
Data Logging and Real Time Clock
• This meter has the capabilities to log up to 199 measurements that can then be transferred to a PC using the HI92000 software.
• Additionally the feature of a real time clock allows time to be stored with GLP data.
ISO Compliant
• The HI93703-11 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).
Last Calibration Date
• The HI93703-11 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.
• Up 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.
Single Beam Design
• The HI93703-11 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.
