This document describes the method for testing the chlorine content of swimming pool water using Hanna HI 93701-0 Free Chlorine and Hanna HI 93734C-0 Total Chlorine test kits
This document is the instruction manual for the Hanna Instruments HI 96734 Free & Total Chlorine High Range Ion Selective Meter (ISM). It provides comprehensive guidance on preliminary examination, unpacking contents, and basic operational procedures. The meter measures free or total chlorine concentration in water samples using a specific reagent set.
The manual details the step-by-step measurement process, including sample preparation, cuvette handling, and instrument operation via keys such as ON/OFF, ZERO/CFM, and READ/TIMER. It also covers calibration procedures using CAL CHECK standards, battery management, error interpretation, and warranty information.
| Range | 0.00 to 10.00 mg/L of Cl2 (Free or Total) |
|---|---|
| Resolution | 0.01 mg/L (0.00-3.50 mg/L); 0.10 mg/L (above 3.50 mg/L) |
| Accuracy | ±0.03 mg/L ±3% of reading @ 25°C |
| Light Source | Tungsten lamp |
| Dimensions | 192 x 102 x 67 mm (7.6 x 4 x 2.6") |
| Weight | 290 g (10 oz.) |
The instrument measures a concentration range of 0.00 to 10.00 mg/L of Cl2.
The meter shuts down after 10 minutes of non-use in measurement mode and after 1 hour of non-use in calibration mode.
A 'Light High' error indicates there is too much light to perform a measurement, requiring the user to check the preparation of the zero cuvette.
