RESIDENTIAL CHLORINE AND TOTAL CHLORINE AND PH
Chlorine is a common chemical used by many people due to its disinfecting properties. Free chlorine can exist in two forms and which form is present depends on the pH. At pH less than 7.6, the dominant form is hypochlorous acid (HOCl) while at pH greater than 7.6 the hypochlorite form (OCl-) becomes dominant. This is important when preventing biological growth in water or keeping swimming pools safe as hypochlorous acid is 100 times more effective as a sanitizer. Total chlorine represents both free chlorine and combined chlorine present. Combined chlorine is chlorine that is bound to nitrogenous substances such as ammonia. In swimming pools it is combined chlorine that we can smell and is irritating to the eyes. The free chlorine measurement is subtracted from the total chlorine measurement to determine how much combined chlorine is present. The HI97710 is designed to measure pH and low range free chlorine and total chlorine in water up to 5.00 mg/L(ppm).
MODERN FEATURES OF THE HI977xx SERIES
– The reagents are packaged and marked A, B for easy use according to instructions.
– The machine will then read out the manganese results directly in the water without any further calculations.
Reagents purchased separately
AUTOMATIC DATA RECORDING AND DATA REVIEW
No need to worry as the photometer will automatically record the last 50 measurements.
Results can be viewed immediately using the Log Recall Menu.
CALIBRATE THE MACHINE WITH CAL CheckTM
CAL Check FeatureTM Hanna's direct, simple procedure to ensure the photometer is working properly.
Simply insert the cuvettes containing Hanna standards into the meter and follow the instructions.
COMMON BATTERY
– Included 1.5V battery provides continuous use of up to 800 measurements.
– BThe battery icon will flash to let you know it's time to change the battery so you never miss a measurement.
LOCATION LOCK ON CUVET CAP
This photometer uses the exclusive HANNA positioning locking system which ensures that the cuvettes are placed in the holder in the same position for accurate measurements every time, ensuring consistency of measurements.
STEP-BY-STEP INSTRUCTIONS ON SCREEN
Setup, calibration and measurement instructions with step-by-step instructions and on-screen animations.
Simply access Guidance Mode at any stage during setup or measurement using the dedicated HELP key.
LCHOOSE A BETTER COMBO
HI97710C comes with CAL Check Standard Solution Set for the meter and a convenient, professional carrying case.
