Bromine, Chlorine, Cyanuric Acid, Iodine, Iron, and pH Photometer

Bromine, Chlorine, Cyanuric Acid, Iodine, Iron, and pH Photometer

The HI97101 is an advanced, portable photometer engineered for comprehensive water quality analysis. It accurately measures six key parameters: bromine, free and total chlorine, cyanuric acid, iodine, iron, and pH. This makes it an indispensable tool for applications ranging from swimming pool and spa maintenance to industrial process water and poultry production.

Advanced Optical System for Superior Accuracy At the core of the HI97101 is a state-of-the-art optical system designed for precision and reliability. Unlike single-beam photometers, our system incorporates a reference detector and a 525 nm narrow-band interference filter. This dual-beam design compensates for any fluctuations in the light source, delivering fast, stable, and repeatable measurements every time.

Key Features:

• No Warm-Up Time: The high-efficiency LED light source requires no warm-up period, allowing you to start testing immediately.
• Intuitive On-Screen Tutorial: An integrated tutorial mode provides clear, step-by-step instructions directly on the display, guiding you through each measurement process.
• CAL Check™ Verification: Hanna's exclusive CAL Check™ feature uses NIST-traceable standards to verify the photometer's performance and accuracy, ensuring your instrument is always functioning correctly.

Multiple Methods, One Meter The HI97101 consolidates several testing methods into a single, user-friendly device:

• Bromine, Chlorine, & Iodine: Measured using the widely recognized DPD method.
• Iron (Low Range): Determined through an adaptation of the TPTZ method.
• pH: Utilizes the classic phenol red method for reliable pH readings.
• Cyanuric Acid: Measured with an adaptation of the turbidimetric method, ideal for pool and spa management.

Chlorine is the most common water disinfectant, and cyanuric acid is essential for stabilizing it in sunlight. Regular monitoring of both parameters, along with pH, ensures effective sanitization and minimizes chemical consumption. Similarly, bromine and iodine serve as effective sanitizing alternatives in cooling towers, spas, and poultry processing, making the HI97101 a versatile solution for diverse industry needs.

How It Works The photometer operates on the Beer-Lambert Law. When a specific reagent is added to the water sample, it reacts with the target parameter to produce a color intensity proportional to its concentration. The HI97101 passes a 525 nm beam of light through the sample, and its silicon photodetector measures the amount of light absorbed. This absorbance value is then converted into a precise concentration reading.

Designed for Field Use

• Stable & Efficient Light Source: The internal reference system and LED light source guarantee consistent readings, unaffected by power fluctuations or ambient temperature.
• High-Quality Optics: A focusing lens and high-quality filters reduce errors from cuvette imperfections and ensure a strong, accurate signal.
• Large Cuvette Size: The 25 mm round cuvette provides a longer path length, which enhances accuracy, especially when measuring samples with low concentrations.
• User-Friendly Interface: The backlit dot matrix LCD features virtual keys and on-screen help, making operation simple and intuitive.
• Durable & Portable: The meter is rugged, waterproof (IP67 rated), and lightweight. It runs on three AA batteries, providing over 800 measurements, and includes an auto-off feature to conserve power.
