Description

Introduction to the HI97761 Photometer

The HI97761 Total Chlorine Ultra Low Range Photometer is an advanced portable device specifically designed for accurately measuring extremely low levels of total chlorine. This meter incorporates a superior optical system that utilizes a reference detector and a narrow band interference filter, ensuring exceptionally fast and repeatable measurements. With its innovative design, the device eliminates errors caused by changes in the light source and imperfections in the glass cuvette, providing reliable results. This photometer is not just a measuring tool; it’s a comprehensive solution for professionals who require precision, durability, and ease of use in their field.

This instrument stands out with its user-friendly features, including a tutorial mode that offers step-by-step, on-screen guidance with animations, making the measurement process straightforward and consistent for every user. The device’s robust IP67-rated waterproof and floating case protects it from the elements, ensuring it performs reliably in any environment. The HI97761 also boasts a built-in timer, which guarantees consistency between tests by managing the reaction time. Furthermore, its auto-logging function automatically saves the last 50 readings, allowing for easy recall and data management. The combination of its advanced technology, rugged design, and thoughtful features makes the HI97761 an indispensable tool for water quality monitoring.

The Superiority of the Optical System

The HI97761 photometer is built on an innovative optical system that utilizes a Light Emitting Diode (LED) as its light source. LEDs are highly efficient, providing more light while consuming less power, which contributes to a longer battery life. They also generate minimal heat, a crucial factor that prevents electronic instability and ensures measurement accuracy. The system also includes a silicon photocell as the light detector and a 525 nm bandpass filter. This advanced configuration, along with a reference detector and a focusing lens, is designed to eliminate common errors, providing the user with more accurate and repeatable readings.

Ensuring Accuracy with CAL Check™ Validation

Hanna’s exclusive CAL Check™ feature provides a simple and stress-free method to verify the photometer’s performance at any time. By using CAL Check™ cuvettes, which are made with NIST traceable standards, users can validate the instrument’s accuracy and ensure it is working properly. The on-screen CAL Check™ screen guides the user step-by-step through the validation process and even allows for user calibration if the instrument is found to be out of specification. This feature is a significant advantage, providing peace of mind and guaranteeing the reliability of your measurements without the need for complex, external calibration procedures.

On-Screen Tutorials and User-Friendly Interface

The HI97761 is designed with the user in mind, featuring an intuitive interface and on-screen tutorial mode. With a dedicated help key, users can access step-by-step instructions and animations at any point in the setup or measurement process. This feature is invaluable for new users or for those performing less frequent tests, ensuring that every measurement is conducted correctly and consistently. The device also displays the unit of measure alongside the reading, which enhances clarity and prevents errors. The backlit 128 x 64 pixel B/W LCD display ensures that readings are visible from any angle, day or night.

Durability and Portability for Field Use

Designed to withstand the rigors of real-world use, the HI97761 is built better than its counterparts. Its IP67-rated body is waterproof and designed to float, providing protection against accidental drops into water. The internal optics are completely sealed from outside dust, dirt, and water, which guarantees top performance in any environment. The photometer is also lightweight at 380 g (13.4 oz.), and its compact dimensions of $142.5\times 102.5\times 50.5$ mm make it highly portable and comfortable to hold for on-the-go testing. The device’s exclusive positive-locking system ensures that the cuvettes are always placed in the same position, which is critical for consistent and accurate readings.

Specific Applications of the HI97761 Photometer

The HI97761 photometer is a vital tool for actively monitoring total chlorine levels. Its ultra-low range capability makes it particularly useful in applications where even minute concentrations of chlorine are significant. Total chlorine is a key indicator in water quality management, as it is one of the oldest and most common forms of disinfection. This device is crucial for ensuring that sufficient chlorine is present to destroy disease-producing microorganisms, thereby improving water quality. Furthermore, it helps control adverse effects such as taste, odor, and the potential formation of harmful disinfection byproducts. This makes the HI97761 essential for municipalities managing drinking water, food and beverage producers, and anyone involved in processes where precise chlorine levels are critical.
