Product Overview

• HI97761 is an advanced portable photometer for measuring ultra-low levels of total chlorine. The instrument provides a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.

• CAL Check instrument performance verification.

• Tutorial mode for step-by-step instructions.

• No warm-up time before measurement.

• *Products classified as dangerous goods can only be shipped by ground transport.

• Better features, better testing

• Let your photometer guide you through setup, calibration, and testing with on-screen tutorials and animations so you always know the next step. Simply use the dedicated help key to access tutorial mode at any stage of the setup or measurement process.

• If the meter is accidentally turned on, the auto-off feature extends battery life, giving you peace of mind and saving energy.

• When battery level drops below 10%, a warning symbol will flash to indicate low battery. When low battery may affect your results, the meter will shut off to avoid erroneous readings caused by low battery.

• Data logging

• Missed a measurement? No need to worry, because your photometer automatically records the last 50 measurements. Use the log recall menu to view results instantly.

• CAL CheckTM verification

• Hanna's exclusive CAL CheckTM feature provides a stress-free, simple way to ensure your photometer is working properly. Simply insert the certified CAL CheckTM standards and let your meter guide you through verification. If your photometer is out of specification for any reason, simply calibrate it with your standards.

• Advanced optical system

• Light emitting diodes (LEDs) provide more light while using less power, and narrow band interference filters deliver more accurate and repeatable readings.

• Built better

• The new IP67-rated body design withstands real-life impacts, drops, and spills, ensuring maximum performance in any environment. Internal optics are sealed from external dust, dirt, and water. In addition, it floats in case you drop the meter into water. The photometer uses a dedicated positive locking system to ensure the cuvette is placed in the same position in the holder every time for accurate readings.

• Portable design

• The backlit LCD display fits comfortably in your hand for mobile testing, or sits on a table for benchtop use, providing at-a-glance readings from any angle, day or night. The included AA batteries provide a lifespan of more than 800 measurements.
