Description

Hanna HI97722: An Advanced Portable Photometer for Water

The Hanna HI97722 is an advanced, portable photometer specifically designed for the precise measurement of cyanuric acid in water. This sophisticated instrument is a culmination of Hanna Instruments’ extensive experience in manufacturing analytical tools, offering an auto-diagnostic capability that ensures reliable and repeatable readings. Its superior optical system, which utilizes a Light Emitting Diode (LED) and a narrow band interference filter, is sealed from external elements like dust, dirt, and water, ensuring top performance in any environment. The device’s robust design is rated to IP67 standards, making it waterproof and even floatable, which is a crucial feature for field measurements where accidents can happen. Additionally, the meter’s exclusive positive-locking system guarantees that cuvettes are placed in the same position every time, a seemingly small detail that is vital for achieving consistently accurate results. All these features are combined into a compact and versatile meter that is ideal for both field and benchtop use.

Enhanced Features for Better Water Testing

The HI97722 photometer is equipped with a range of advanced features that simplify the testing process and enhance data management. The built-in tutorial mode is an invaluable asset, providing users with step-by-step, on-screen instructions and animations that guide them through the measurement procedure. This ensures that even novice users can perform tests correctly from the very beginning, with all necessary steps for sample preparation and reagent handling clearly outlined. For long-term data management, the instrument includes an auto-logging feature that automatically saves the last 50 measurements, which can be easily viewed and managed through the Log Recall menu. This eliminates the worry of missing a crucial reading. The device also includes an auto-off feature to prolong battery life, activating after 15 minutes of inactivity, or 30 minutes if a zero measurement has been performed.

A System for Guaranteed Measurement Accuracy

One of the most important features of the Hanna HI97722 is its exclusive CAL Check™ functionality. This stress-free system provides a straightforward method for users to validate the instrument’s performance at any time. By simply inserting the certified CAL Check™ standards, which are made with NIST traceable standards, the meter guides the user through a validation process. If the meter is found to be out of specification, the user can easily perform a calibration to their standard. This feature, along with the sophisticated optical system, ensures that the instrument consistently provides accurate and repeatable results. The optical system incorporates a reference detector that compensates for any drifts caused by power fluctuations or changes in ambient temperature, providing a stable light source for all measurements. This is a significant improvement over traditional photometers and a key reason for the HI97722’s superior reliability.

Unlocking the Full Power of Light

The optical system of the HI97722 is a marvel of engineering, built to provide more accurate and repeatable readings with greater efficiency. It leverages a Light Emitting Diode (LED) as its light source, which is far superior to older tungsten lamps. LEDs are more luminous and use less power, which directly translates to a longer battery life of over 800 measurements without the backlight. They also produce very little heat, a factor that can otherwise negatively impact electronic stability. The system’s narrow band interference filter, with an 8 nm bandwidth, ensures greater wavelength accuracy, resulting in a brighter, stronger signal and higher measurement stability. A key component is the focusing lens, which collects all light exiting the cuvette. This innovative design eliminates errors that could arise from cuvette imperfections or scratches, and it also removes the need for cuvette indexing.

Real-World Applications of This Photometer

The HI97722 photometer is an essential tool for a variety of applications where the monitoring of cyanuric acid is critical. Its primary purpose is to measure cyanuric acid levels in water, which is a key parameter in pool and spa maintenance. Cyanuric acid is used as a stabilizer for chlorine to prevent its rapid degradation from ultraviolet light. Maintaining the correct concentration is vital for effective sanitization and bather comfort. Too little cyanuric acid means chlorine will be ineffective, while too much can lead to “chlorine lock,” where the chlorine becomes too stable and loses its sanitizing power. The meter’s portability and rugged design, with an IP67 waterproof rating, make it perfect for field use by pool technicians, public health officials, or homeowners who need to check water quality on-site. The ease of use, thanks to the tutorial mode, makes it accessible for anyone to perform these critical tests and ensure water safety and clarity.

Designed for Versatility and User Convenience

The design of the HI97722 is centered on user convenience and versatility, making it suitable for a wide range of users, from professional technicians to casual users. Its compact and ergonomic body is made to fit comfortably in hand for on-the-go testing, but it can also sit on a table for benchtop use. The backlit LCD display provides clear, at-a-glance readings from any angle, ensuring visibility in all lighting conditions, day or night. The straightforward keypad with direct and functional keys simplifies navigation, with dedicated keys for context-sensitive help, menu access, and power. The meter’s thoughtful design also includes a positive-locking system for the cuvette holder, a small but important detail that ensures consistent and accurate placement every time, eliminating potential measurement errors.

Unwavering Commitment to Quality and Reliability

Every aspect of the Hanna HI97722 photometer, from its internal components to its physical construction, reflects a commitment to quality and reliability. The instrument is built to withstand the knocks, drops, and spills of real-life use, with an IP67-rated floating case. It is supplied with high-quality accessories, including sample cuvettes, caps, and alkaline batteries. The product also comes with an instrument quality certificate, providing assurance of its performance and manufacturing standards. The meter’s battery management is another testament to its thoughtful design; it will alert the user when the battery level is low and will even shut down to prevent inaccurate readings when the power is too low to maintain proper operation. For the best testing experience, the Cyanuric Acid Photometer Kit is also available, which includes certified CAL Check™ standards.

Unmatched Value and Global Authenticity

The Hanna HI97722 Cyanuric Acid Photometer is not just a high-quality instrument; it is a smart investment in accurate and reliable water testing. The convenience of its features, combined with the precision of its optical system and the reassurance of its CAL Check™ functionality, makes it a standout product in its class.
