Hanna HI97711: The Ultimate Water Quality Photometer

The Hanna HI97711 Free and Total Chlorine Photometer stands as a testament to Hanna Instruments’ decades of experience in creating analytical instruments. Designed for both novices and seasoned professionals, this auto-diagnostic, portable device combines laboratory-grade precision with an exceptionally user-friendly interface. At its core is a sophisticated optical system that utilizes a Light Emitting Diode (LED) and a narrow band interference filter, ensuring highly accurate and repeatable readings with minimal power consumption and heat generation. The meter’s design is robust and engineered to withstand real-world conditions, featuring an IP67 rating that makes it waterproof and even capable of floating if accidentally dropped in water. This durability, combined with a positive-locking system for cuvette placement, guarantees consistent results every time you take a measurement.

Advanced Optical Systems for Superior Measurement

The sophisticated optical system is one of the key differentiators of the HI97711. Unlike older systems that rely on tungsten lamps, the HI97711 uses an LED light source, which is far more energy-efficient and provides a more stable light output. The narrow band interference filter further enhances the device’s accuracy by ensuring a more precise wavelength is used for measurement, leading to greater stability and less wavelength error. This advanced technology, coupled with an internal reference detector, effectively compensates for any light source drifts caused by power fluctuations or ambient temperature changes, providing a consistently stable light source for both blank and sample measurements. The intelligent design even includes a focusing lens that gathers all light exiting the cuvette, which eliminates errors from potential cuvette imperfections and scratches.

Calibration and Validation with Exclusive CAL Check

Ensuring the reliability of your measurements is made stress-free with Hanna’s exclusive CAL Check™ feature. This function allows users to validate the instrument’s performance at any time using certified, NIST-traceable standards. The meter guides you through a straightforward validation process, and if the device is found to be out of specification, it provides the option for a user calibration. This unique capability provides peace of mind, assuring that your results are always accurate and dependable. The on-screen tutorials and animations make the entire process simple and accessible, eliminating any guesswork and guiding you step-by-step through the validation and calibration procedures.

Streamlined Operations with an Intuitive User Interface

The HI97711 is designed for an easy and seamless user experience, making water quality testing accessible to anyone. The built-in tutorial mode is a stand-out feature, guiding users step-by-step through the measurement process, including sample preparation, required reagents, and quantities. The keypad is simple and direct, with dedicated keys for power, menu, and context-sensitive help. This intuitive design allows for quick and confident operation, whether you are in the field or at a lab bench. Furthermore, the meter’s auto-logging feature automatically saves the last 50 measurements, which can be easily viewed using the Log Recall menu, so you never have to worry about missing or forgetting a reading.

A Versatile Tool for a Wide Range of Applications

The HI97711 photometer is an essential tool for monitoring water quality, and its versatility makes it suitable for a wide array of applications. Given that chlorine is a widely used disinfectant, this instrument is indispensable in managing water quality for drinking water, wastewater, and swimming pools. In municipal water treatment facilities, it’s crucial for ensuring that the proper level of chlorine is maintained for public safety without exceeding regulatory limits. For wastewater management, the meter helps in verifying that post-treatment effluent meets environmental discharge standards. Swimming pool operators can use the HI97711 to quickly and accurately measure chlorine levels, ensuring a safe and clean swimming environment for bathers. Its compact, portable design makes it perfect for on-site field measurements as well as benchtop use.

Designed for Durability and Long-Term Performance

The HI97711 is built to last. Its IP67-rated body provides superior protection against dust, dirt, and water ingress, ensuring top performance in any environment. The internal optics are sealed to prevent damage, and the floating case design means you won’t lose your meter if it takes an accidental plunge. The device is powered by three 1.5V AA alkaline batteries, providing a long-lasting life of more than 800 measurements without the backlight. An auto-off feature further prolongs battery life by shutting down the meter after 15 minutes of inactivity, or 30 minutes if a zero reading has been performed.
