Hanna HI93102 Portable Multiparameter Turbidity and Ion Specific Meter

Description

The Ultimate Water Analysis Solution

The Hanna HI93102 is a portable multiparameter meter designed for comprehensive water analysis, offering a powerful combination of accuracy and convenience in a single, ergonomic device. This advanced instrument is engineered to measure a wide range of critical parameters, including turbidity, free and total chlorine, cyanuric acid (CYAC), pH, bromine, iodine, and low range iron. Its sophisticated yet user-friendly microprocessor ensures that measurements are taken quickly, accurately, and with high repeatability, making it an ideal tool for both field work and laboratory settings.

This meter stands out for its robust feature set, which includes EPA compliance for turbidity measurements using the nephelometric principle. It utilizes AMCO-AEPA-1 standards, which are recognized as primary standards by the USEPA. These non-toxic standards are reusable and have a long shelf life, providing reliable and consistent results. The HI93102 also offers custom calibration points, allowing users to calibrate the meter to their specific needs. With the capability to store up to 25 measured samples, complete with time and date, it provides a convenient logging function for data management.

The Ingenuity of Its Design and Technology

The HI93102’s design is a testament to modern engineering, successfully miniaturizing complex electronics to offer laboratory-grade accuracy in a compact, portable unit weighing just over one pound. A key innovation is the exclusive cuvette locking system, which ensures the cuvette is always placed in the same position for consistent path length, guaranteeing repeatable measurements. The meter also incorporates an array of helpful features for the user, such as an automatic shut-off function that can be set from 10 to 60 minutes to conserve battery life.

Furthermore, the meter includes a battery status indicator that warns the user when the battery is insufficient for a reliable measurement. For diagnostic purposes, it displays helpful error codes to alert the user to issues like low or high light, or if a sample is out of range. The meter’s GLP (Good Laboratory Practice) function allows users to recall calibration information, including the date and time, with a single button press. This combination of portability, robust features, and user-centric design makes the HI93102 a premier choice for professionals who require precise and reliable water quality analysis on the go.

Essential Parameters for Water Quality Assurance

The HI93102 is a critical tool for ensuring water quality across a variety of applications, from drinking water and wastewater treatment to pools and spas. Turbidity, one of the primary parameters it measures, is a vital indicator of drinking water quality and serves as an effective safeguard against pathogens. In natural water, turbidity measurements help gauge overall water quality and its suitability for aquatic life.

The meter’s ability to measure both free and total chlorine is particularly significant for disinfection. Free chlorine is the amount available for sanitation, while total chlorine includes both free and combined forms. By measuring both, operators can determine if there is enough chlorine to effectively disinfect water. The instrument also tests for cyanuric acid, a key stabilizing reagent for chlorine in pools and spas that slows down its decomposition from UV rays.

Measuring Beyond the Basics of Water Quality

Beyond its core functions, the HI93102 also measures other crucial parameters. Bromine, for instance, is a less volatile and more stable alternative to chlorine, making it a popular choice for sanitizing pools, spas, and drinking water systems. Daily monitoring of bromine levels is essential to prevent equipment damage and ensure user safety.

Additionally, the meter’s ability to measure low-range iron is important for various applications. Although iron is naturally present in water at low concentrations, high levels can be problematic, causing stains on laundry and kitchenware, altering the taste of water, and promoting bacterial growth. Monitoring iron is also critical in industrial settings, such as water cooling and heating systems, where it can indicate ongoing corrosion, and in mining wastewater to prevent environmental contamination.

A Tale of Two Principles: Turbidimetry and Colorimetry

The HI93102 operates on two distinct principles to deliver its multiparameter capabilities: turbidimetry and colorimetry. In its turbidimetric mode, which measures turbidity, the meter uses a pure green LED light source and a 90° scattered light detector to apply the nephelometric principle. When light passes through a sample, particles within the water scatter the light in all directions, and the meter measures the intensity of this scattered light to determine the turbidity.

For its colorimetric measurements—which include chlorine, pH, and other ions—the meter relies on the Beer-Lambert Law. A specific reagent is added to the water sample, causing a color change. The concentration of the substance is directly proportional to the intensity of the color change. The meter then uses a narrow band interference filter at 525 nm (green) and a silicon photodetector to measure the absorbance of this specific light wavelength. As the color intensity increases, so does the light absorption, allowing for a precise concentration measurement.

Precision Measurement Across All Parameters

The HI93102 is lauded for its high precision across all its measurement functions. Whether it’s the 0.01 NTU resolution for turbidity or the ±0.1 pH accuracy, the meter is built for demanding analytical tasks. This level of precision is critical for professional use, where even minor deviations in water quality can have significant health and safety implications or impact industrial processes.

Its comprehensive suite of measurement capabilities, from determining disinfectant levels to monitoring for contaminants like iron, makes it an all-in-one solution for water quality management. The meter’s ability to handle multiple parameters with such a high degree of accuracy reduces the need for multiple instruments, streamlining workflows and providing a more efficient way to conduct thorough water analysis. This efficiency, combined with its portability and ease of use, positions the HI93102 as a top-tier instrument in its class.
