Hanna Free Chlorine and UHR Total Chlorine Portable Photometer-Kit - HI97771C

The Free Chlorine and Ultra High Range Total Chlorine Portable Photometer HI97771C is designed for efficient and accurate measurement of chlorine in a wide range of water treatment, food processing, and industrial disinfection applications. With its advanced optical system featuring a reference detector and high-quality interference filters, the HI97771C delivers rapid, reliable results for both free chlorine (0.00–5.00 mg/L) and ultra high range total chlorine (up to 500 mg/L).

The instrument requires no warm-up time, provides a user-friendly tutorial mode, and includes a robust logging memory to automatically store up to 50 measurements. Its construction is IP67 rated, ensuring maximal protection against dust and temporary immersion in water, making it suitable for use in laboratory, field, and industrial settings where high chlorine levels are common.

• Equipped with advanced optical technology for enhanced measurement performance and repeatability.
• Measurement methods adapted directly from EPA 330.5 (DPD) for free chlorine and Standard Methods 4500-Cl. for total chlorine for regulatory compliance.
• Supports round glass cuvettes with a 24.6 mm (22 mm inner) diameter for standardized sample preparation.
• The unit is powered by three 1.5V AA batteries, providing over 800 measurements on a single set (without backlight).
• Onboard GLP compliance features allow retrieval of calibration date, time, and calibration status at any time.
• The device operates in harsh environmental conditions ranging from 0 to 50°C and up to 100% relative humidity.
• Large, clear backlit LCD (128 x 64 pixels) ensures easy readability in lab and field environments.
• Automatic power-off function to conserve battery after 15–30 minutes of inactivity.
• Light source utilizes a high-quality LED with a narrow band interference filter (525 nm) and silicon photocell detector for maximum accuracy.
• Ideal for water treatment plants, food industry hygiene monitoring, and high-chlorine process water analysis.

Typical industrial, laboratory, and water treatment applications include environmental monitoring, regulatory compliance in food and beverage washing, disinfection monitoring in medical equipment cleaning, and ultra-high range chlorine checks in industrial process water systems using Hanna instruments.
