HI97104 is an advanced portable photometer for the measurement of pH, alkalinity, cyanuric acid, free chlorine, and total chlorine in water. This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.
No warm up time before taking a measurement
Tutorial mode for step-by-step instructions
Uses either powder or cost saving liquid reagents
Chlorine is a common chemical used by many due to is disinfection properties. Free chlorine can exist in two forms and which form is present is based on the pH. At pH less than 7.6 the predominate form is hypochlorous acid (HOCl) while at pH greater than 7.6 the hypochlorite (OCl^–) form becomes predominate. This is very important when it comes to preventing biological growth in water or keeping a swimming pool safe since hypochlorous acid is 100 times more effective as a sanitizer. Total chlorine represents both the free chlorine and combined chlorine present. Combined chlorine is the chlorine bound to nitrogen substances such as ammonia. In swimming pools combined chlorine that we can smell and is irritating to the eyes. The free chlorine measurement is subtracted from the total chlorine measurement in order to know how much combined chlorine is present. HI97104 is designed to measure swimming pool key water quality paramters. These parameters, in addition to chlorine, are pH, alkalinity, and cyanuric acid.
The HI97104 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods, reviewing GLP data, recalling the last 50 measurements, and customizing the meter to user preferences
HI97104 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries. The compact design fits comfortable in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75″) by 37 mm (1.6″) and is backlit for easy viewing under all conditions.
LED that generates very little heat

8 nm narrowband interference filter that is accurate to +/- 1 nm and offers 25% increase in light efficiency.

Reference detector that modulates the voltage to LED for consistent light output.

A concave focusing lens that reduces errors from imperfections in the cuvette
On-Screen Features
CAL Check
Advanced features including CAL-Check to verify performance, GLP for last calibration date, setup options and the ability to see all accessories used with the meter.
Tutorial Mode
When enabled, the tutorial mode will guide the user step by step through the measurement process .
Method Options
Choice of powder or economical liquid reagents for chlorin measurments.
