Hanna HI97769 Anionic Surfactants Photometer

The device’s design prioritizes durability and user convenience. Its waterproof and floating IP67-rated casing protects it from dust, dirt, and water, making it suitable for various environments. The built-in timer ensures consistency between tests, while error messages alert users to potential problems like a missing cap or high zero readings. It automatically logs the last 50 readings, and the auto-shut off feature extends battery life. With a backlit LCD display and a compact design, it is ideal for both on-the-go and benchtop use. The provided AA batteries offer a long life, allowing for more than 800 measurements without the backlight.

Understanding the HI97769 Anionic Surfactants Photometer

The HI97769 photometer is a cutting-edge instrument that stands out in the field of portable water quality testing. Its advanced LED optical system is a key feature, utilizing a reference detector and a focusing lens to mitigate errors that can arise from changes in the light source or imperfections in the glass cuvette. The LEDs themselves are highly efficient, producing a great deal of light while consuming minimal power. Furthermore, they generate very little heat, which helps maintain the electronic stability of the device. This combination of features ensures that the measurements are not only fast but also highly accurate and reliable.

Built-In Features for Better Performance

The HI97769 is equipped with several features that enhance its performance and ease of use. The on-screen tutorial mode is particularly helpful, guiding users with step-by-step instructions and animations throughout the measurement process. This functionality ensures that even novice users can operate the device correctly. The built-in reaction timer is another critical component, guaranteeing consistent timing for each test. The device’s display shows the unit of measure alongside the reading and can alert users to potential issues with error messages. It also logs the last 50 readings automatically, which is a convenient feature for data tracking and review.

Ensuring Accuracy and Precision with CAL Check™

Hanna’s exclusive CAL Check™ feature provides a simple and reliable method for verifying the photometer’s performance. Using NIST traceable standards, users can validate the instrument at any time. The dedicated CAL Check screen guides the user through a step-by-step validation process and allows for user calibration if the instrument is found to be out of specification. This capability ensures that the device maintains its accuracy over time, providing users with confidence in their results.

A Design Engineered for Real-World Durability

The HI97769 is designed to withstand the rigors of field use. Its IP67 waterproof and floating case protects it from accidental submersion and exposure to dust and dirt, making it ideal for harsh environments. The internal optics are sealed, providing an extra layer of protection. This robust construction, combined with its portable design, makes it suitable for on-the-go testing. The device’s exclusive positive-locking system ensures that the cuvette is always placed in the same position, which is crucial for achieving consistent and accurate readings.

Specialized Applications of the HI97769 Photometer

The HI97769 is specifically engineered for the measurement of anionic surfactants. This capability is vital in numerous applications, particularly in environmental monitoring and industrial processes. In wastewater treatment, monitoring anionic surfactant levels is crucial for ensuring the effectiveness of treatment processes and compliance with environmental regulations. In the detergent and cleaning industry, it is used for quality control to ensure that products contain the correct concentration of active ingredients. Environmental agencies and research institutions use this device to assess water quality in rivers, lakes, and other water bodies, as high levels of surfactants can be harmful to aquatic life. Furthermore, it is adapted from the US EPA Method 425.1 and Standard Methods for the Examination of Water & Wastewater, 20th Edition, 5540C, which confirms its suitability for official and standardized testing.
