Key Features for Exceptional Performance

The Hanna HI88713 is equipped with several key features that set it apart. One of its most notable attributes is the four distinct measurement modes: FNU, FAU, and both ratio and non-ratio NTU modes. This versatility allows the meter to handle a wide range of turbidity levels, from low-turbidity drinking water to highly turbid wastewater. For instance, the NTU ratio mode can measure up to 4000 NTU, while the FNU mode is designed for measurements up to 1000 FNU. Another significant feature is the ISO 7027 compliance, which is achieved through the use of an infrared LED light source. This specific light source is crucial as it eliminates color interference in the sample, ensuring more accurate turbidity readings compared to methods that use visible light.

The meter also features a powerful calibration function that allows for two, three, four, or five-point calibration using the supplied standards. This flexibility ensures that the instrument can be precisely calibrated for a variety of applications and measurement ranges. Additionally, users have the option to use their own standards, and the calibration points can be modified accordingly. The GLP (Good Laboratory Practice) function is another valuable feature, providing complete traceability of calibration conditions, including the specific calibration points, date, and time. This is particularly important for quality assurance and regulatory compliance in professional laboratory settings. The meter’s ability to log up to 200 measurements and transfer them to a PC via USB for further analysis highlights its modern design and suitability for detailed data management.

Operational Principles and Advanced Technology

The operation of the HI88713 is based on sophisticated optical principles that utilize both scattered and transmitted light to determine turbidity. When a light beam from the infrared LED passes through a liquid sample, it is scattered in various directions by suspended particles. The meter’s optical system is comprised of two key detectors: a scattered light detector positioned at a 90° angle and a transmitted light detector at a 180° angle. The specific measurement mode determines which of these detectors is used to calculate the final turbidity value. For example, in non-ratio modes (FNU and NTU), the turbidity value is calculated solely from the signal received by the 90° scattered light detector.

In contrast, the ratio turbidimeter mode utilizes signals from both the scattered and transmitted light detectors. An advanced microprocessor within the meter uses an effective algorithm to process these signals, allowing it to correct for and compensate for any color-related interferences. This dual-detector approach results in higher accuracy, especially in highly turbid samples. One of the most critical factors in a turbidimeter’s performance is its stray light, which can cause inaccurate readings in low-turbidity samples. The HI88713’s optical system is meticulously designed to minimize stray light to less than 0.1 NTU (0.05 EBC), ensuring highly accurate and reliable results even in very clear samples. The use of AMCO AEPA-1 standards, which are NIST-traceable, guarantees that the meter’s measurements are precise and reliable, upholding the highest standards of quality and traceability.

Wide-Ranging Applications for Diverse Industries

The versatility of the Hanna HI88713 makes it an indispensable tool across numerous industries and applications. A primary use for this meter is in drinking water quality assessment. Turbidity is a key indicator of water purity, and controlling it is a vital safeguard against pathogens. The meter’s ability to provide accurate readings in low turbidity ranges makes it perfectly suited for monitoring treated drinking water, ensuring it meets safety standards. Another crucial application is in wastewater treatment plants. Historically, turbidity was a primary parameter for monitoring wastewater; today, it is essential for verifying that treated wastewater values fall within regulatory standards before it is discharged. The HI88713’s high-range measurement capabilities (up to 4000 NTU) make it ideal for this purpose.

The meter is also widely used in environmental monitoring, where turbidity measurements help gauge the general quality of natural water bodies like rivers, lakes, and streams. This is important for assessing the health of aquatic ecosystems and their compatibility with various aquatic organisms. For industries such as food and beverage production and pharmaceutical manufacturing, turbidity is a critical quality control parameter. The HI88713 can be used to monitor the clarity of products like beer, fruit juices, and syrups, or to ensure the purity of solutions used in drug manufacturing.
