CHLORINE IN CLEAN WATER

drinking-water-tap-6

Chlorine is a common chemical used by many people due to its disinfecting, oxidizing, and bleaching properties. In swimming pools, drinking water, and food processing, chlorine is used to disinfect and prevent bacterial growth. In metal finishing, it is used as an oxidizer to convert cyanide in wastewater to cyanide while in the pulp and paper industry, it is used to bleach wood pulp to give the paper its white color. The HI97790 is designed to measure free and total chlorine in water at low levels from 0 to 5.00 mg/L (ppm).

MODERN FEATURES OF THE HI977xx SERIES

WHAT IS THE DIFFERENCE BETWEEN HI97711 AND HI97790?

– HI97790 uses only aqueous reagents HI93701-T and HI93701-F (cannot use powder form)

– HI97790 can measure total chlorine and free chlorine in 1 MEASUREMENT with HI93701-T reagent

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.

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 Check^_TM

CAL Check Feature^_TMHanna's direct, simple procedure to ensure the photometer is working properly.
