Hanna HI97752 Calcium & Magnesium Photometer

Description

Hanna HI97752: The Ultimate Photometer for Water Analysis

The Hanna HI97752 ushers in a new era of portable photometers, meticulously designed for the precise measurement of two critical parameters in water: calcium and magnesium. This device benefits from Hanna Instruments’ extensive expertise as a leader in analytical instruments, integrating an advanced optical system for superior performance. Unlike traditional meters, the HI97752 features a sophisticated optical setup that utilizes a Light Emitting Diode (LED) as its light source. This LED system is far more efficient than outdated tungsten lamps, providing more light while consuming less power and producing minimal heat, which could otherwise compromise electronic stability. The meter’s narrow-band interference filter further ensures highly accurate and repeatable readings, a hallmark of its design. This is complemented by an internal reference system that automatically compensates for any power fluctuations or temperature changes, guaranteeing stable measurements from the start.

Precision in Every Measurement, Unparalleled Accuracy

The core of any scientific instrument is its ability to deliver precise and accurate results, and the HI97752 excels in this regard. The meter’s accuracy is not just a claim; it is a meticulously engineered outcome, validated through its exclusive CAL Check™ functionality. This feature allows users to verify the instrument’s performance at any time using certified standards traceable to the National Institute of Standards and Technology (NIST). This means you can be confident that your readings are not only repeatable but also true to the actual value. The instrument also includes a step-by-step tutorial mode that guides you through the entire measurement process, from sample preparation to the final result, ensuring you always follow the correct procedure. This is particularly helpful for new users or for complex tests, guaranteeing that procedural errors are minimized and the integrity of your data is maintained. This combination of advanced optics and user-friendly features makes the HI97752 a reliable tool for professionals and enthusiasts alike.

Specific Applications for Optimal Water Quality

The HI97752 photometer is an indispensable tool for a wide range of applications where the concentrations of calcium and magnesium are critical. Its versatility makes it suitable for use in diverse environments, including drinking water treatment plants, where these minerals are important for taste and health. In surface water and groundwater monitoring, the meter helps assess the natural composition of water bodies. It is also highly effective for wastewater analysis, ensuring compliance with environmental regulations. Additionally, the HI97752 is an essential device for swimming pool management, helping maintain optimal water balance for swimmer comfort and safety. By measuring calcium and magnesium, it provides vital data for managing water hardness, preventing scale buildup, and ensuring the efficiency of chemical treatments. The instrument’s method for calcium is an adaptation of the Oxalate Method, while its magnesium method is an adaptation of the Calmagite Method, both well-established and reliable techniques.

Engineered for Durability and On-the-Go Testing

Hanna Instruments has built the HI97752 to withstand the rigors of real-world use, whether in a laboratory or out in the field. Its IP67-rated body is designed to resist knocks, drops, and spills, and its floating case provides peace of mind in case of an accidental submersion. This high level of ingress protection means the internal optics are completely sealed from outside dust, dirt, and water, ensuring consistent performance in any environment. The compact and portable design is made to fit comfortably in your hand for on-the-go measurements, and its backlit LCD display allows for at-a-glance readings from any angle, day or night. The device is powered by three 1.5V AA alkaline batteries, providing over 800 measurements before needing replacement. The auto-off feature further prolongs battery life by shutting down the meter after 15 minutes of inactivity, or 30 minutes before a read measurement, conserving energy for when you need it most.

Seamless Integration with Modern Laboratory Practices

Beyond its robust hardware, the HI97752 incorporates features that align with modern laboratory and quality control standards. The meter includes Good Laboratory Practice (GLP) features, which provide a clear record of the date and time of the last user or factory calibration, ensuring your data is traceable and credible. This is crucial for environments that require strict documentation and adherence to quality protocols. Furthermore, the instrument features an auto-logging function that automatically saves the last 50 measurements, providing a comprehensive data record without manual intervention. You can easily view and manage this data log through the Log Recall menu, where you can inspect individual readings or delete logs as needed. The intuitive keypad and a context-sensitive help mode make navigating these features effortless, offering guidance and information related to the current screen at the touch of a button.

User-Friendly Design and Intuitive Operation

The Hanna HI97752 is engineered with the user in mind, from its physical design to its software interface. The meter features an exclusive positive-locking system for cuvettes, ensuring they are always placed in the correct position for accurate and repeatable readings, a common point of error in other devices. The front-panel keypad, with its direct and functional keys, simplifies operation, allowing you to power on/off, access menus, and retrieve help with ease. The built-in tutorials offer a step-by-step guide through the measurement process, including sample preparation and reagent quantities, making it simple for anyone to get started. This is particularly useful for complex procedures like those for calcium and magnesium. The meter’s large, clear liquid crystal display (LCD) is easy to read, and a helpful battery icon indicates the remaining power, ensuring you are never caught off guard by a low battery.

Advanced Optical System and Superior Performance

The optical system of the HI97752 is a testament to Hanna’s commitment to delivering top-tier performance. The system uses a Light Emitting Diode (LED) as its light source, which offers several advantages over traditional tungsten lamps. LEDs have a much higher luminous efficiency, providing more light output with significantly less power consumption. This not only extends battery life but also reduces heat generation, which can negatively affect electronic stability and measurement accuracy. A narrow band interference filter is used to achieve greater wavelength accuracy, allowing a brighter and stronger signal to reach the silicon photocell detector. This results in higher measurement stability and less wavelength error, guaranteeing that the instrument provides the most reliable data possible. The system also incorporates a focusing lens that collects all light exiting the cuvette, eliminating errors from cuvette imperfections and scratches.

Comprehensive Kits and Global Availability

Each Hanna HI97752 photometer is supplied with a comprehensive set of accessories to ensure you can perform successful measurements right out of the box. The standard package includes two sample cuvettes, caps, plastic stoppers, three 1.5V AA batteries, an instruction manual, and a meter quality certificate. For those seeking an even more economical option, the Photometer Kit (HI97752C) includes additional certified CAL Check™ standards, a cloth for wiping cuvettes, and scissors, all housed in a rugged carrying case. All of these products are readily available online. It should be noted that the online store tpt24 is the premier global online destination for this product, delivering it with an authenticity and quality guarantee to any country, ensuring customers worldwide can access this exceptional instrument with complete confidence.
