Hanna HI97742 Iron & Manganese Low Range Photometer

Description

Unveiling The Hanna HI97742 Photometer

The HI97742 is a sophisticated portable photometer engineered by Hanna Instruments, a leader in analytical instrumentation with decades of experience. This advanced device is specifically designed for the precise measurement of iron and manganese levels in water, making it an indispensable tool for a wide range of applications from environmental monitoring to quality control in water treatment facilities. The photometer’s superior optical system, which incorporates a Light Emitting Diode (LED) and a narrow band interference filter, ensures highly accurate and repeatable measurements. This innovative design provides more light with less power consumption, generates minimal heat to avoid affecting electronic stability, and offers greater wavelength accuracy, resulting in superior measurement stability and reduced wavelength error. The robust, floating, and waterproof IP67 case protects the internal optics from external dust, dirt, and water, ensuring top performance even in challenging environments.

A User-Friendly Guide To Operations

One of the standout features of the HI97742 is its user-friendly interface and on-screen tutorial mode, which simplifies complex testing procedures. This intuitive functionality guides users step-by-step through the entire measurement process, including sample preparation, reagent addition, and testing. This built-in assistance is invaluable for both novice and experienced operators, ensuring consistent and reliable results. The device also includes an auto-off function that prolongs battery life by shutting down the meter after 15 minutes of inactivity, or 30 minutes before a reading is taken, providing peace of mind and energy savings. When the battery level drops below 10%, a warning symbol blinks, and the meter will automatically shut down if the low power level could potentially affect the accuracy of the readings, preventing erroneous data. The keypad with its dedicated help key makes navigating the meter’s functions and accessing contextual help simple and efficient.

Ensuring Accuracy With CAL Check Technology

The HI97742 is equipped with Hanna’s exclusive CAL Check™ feature, which offers a simple and reliable way to validate the instrument’s performance at any time. By using certified, NIST traceable CAL Check standards, users can easily verify if the photometer is operating within its specified accuracy. The meter’s on-screen prompts guide the user through the validation process, and if the device is found to be out of specification, it can be easily calibrated to the user’s standard. This functionality is crucial for maintaining data integrity and ensuring that all measurements are precise and accurate. The instrument’s optical system is also designed to eliminate errors from cuvette imperfections and scratches, as a focusing lens collects all light exiting the cuvette, further enhancing accuracy and reproducibility.

Versatility And Portability For Any Setting

This compact and versatile photometer is designed for both on-the-go field testing and stationary benchtop use. Its portable design fits comfortably in the hand, and the backlit LCD display provides clear, at-a-glance readings from any angle, whether day or night. The device is also equipped with a positive-locking system for the cuvette holder, which ensures that the cuvette is always placed in the same position, contributing to highly accurate readings. The supplied AA batteries provide a long operational life of over 800 measurements without the backlight, making it a reliable tool for extended use in the field. The meter’s ability to float, in case it is dropped into water, adds an extra layer of protection and durability.

Comprehensive Data Management And Features

The HI97742 streamlines data management with its auto-logging function, which automatically saves the last 50 measurements. Users can easily view the results instantly using the Log Recall Menu, a feature that prevents the loss of critical data. The meter also incorporates Good Laboratory Practice (GLP) features, which provide valuable information on the date and time of the last user or factory calibration. This ensures traceability and helps maintain high standards of quality assurance. The meter’s software also allows for simple customization of settings, including backlight intensity, display contrast, date and time format, language, and beeper function, allowing users to tailor the instrument to their specific needs and preferences.

The Science Behind The Measurement Process

The HI97742 employs the principles of photometric chemical analysis to determine the concentration of iron and manganese in water. This process relies on the Lambert-Beer Law, which states that the fraction of light absorbed by a substance is directly proportional to its concentration. The meter utilizes specific chemical reactions between the water sample and a reagent to produce a light-absorbing compound. The instrument’s internal reference system, which includes a reference detector, compensates for any power fluctuations or changes in ambient temperature, providing a stable source of light for both zeroing and sample measurements. This advanced optical and chemical-based measurement system ensures that the readings are not only repeatable but also a true representation of the analyte concentration in the sample. The methods used are an adaptation of the TPTZ Method for iron and the 1-(2-Pyridylazo)-2-Naphthol PAN Method for manganese.

Versatile Applications In Water Quality Control

The HI97742 is an essential tool for professionals and organizations involved in water quality assessment. The ability to accurately measure low-range iron and manganese is critical in many sectors. For instance, in municipal water treatment plants, monitoring these parameters helps ensure that drinking water is safe, clean, and free from unpleasant taste or color. In industrial settings, the photometer can be used to monitor process water, preventing scale buildup and equipment corrosion. Additionally, environmental agencies can use the device for field testing of lakes, rivers, and groundwater to assess the impact of pollution and natural processes on water ecosystems. The device’s robust design and long battery life make it ideal for field surveys and remote monitoring, providing a reliable solution for comprehensive water analysis in any environment.
