This document is an instruction manual for the HI 96724C Free & Total Chlorine Ion Selective Meter from Hanna Instruments, providing information on its usage and precautions.
The HI 96724 is an auto-diagnostic portable microprocessor meter designed for measuring free and total chlorine content in water. It features an advanced optical system with a tungsten lamp and narrow band interference filter, ensuring accurate and repeatable readings according to USEPA Method 330.5 and Standard Method 4500-Cl G.
The instrument includes user-friendly functions such as CAL CHECK validation, GLP mode for data integrity, and an auto-shut-off feature. It operates using a positive-locking cuvette system and requires specific reagents (HI 93701A-T, B-T, or C-T) to perform measurements in the range of 0.00 to 5.00 mg/L.
| Range | 0.00 to 5.00 mg/L of Cl2 (Free or Total) |
|---|---|
| Resolution | 0.01 mg/L from 0.00 to 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 |
| Environment | 0 to 50°C (32 to 122°F); max 95% RH non-condensing |
| Battery Type | 1x9 volt |
| Auto-Shut off (Measurement) | After 10' of non-use in measurement mode |
The meter uses an adaptation of the USEPA Method 330.5 for wastewater and Standard Method 4500-Cl G for drinking water.
The instrument requires HI 93701A-T, HI 93701B-T, or HI 93701C-T reagents depending on the specific chlorine type being measured.
