This document is about the user manual of Hanna instrument's multiparameter ion specific meters. It introduces the functions and features of the meter and how to use it.
This manual provides instructions for the Hanna Instruments Multiparameter Ion Specific Meters, specifically models HI 93710 (pH/Chlorine) and HI 93724 (Cyanuric Acid/pH). The devices are portable, microprocessor-based colorimeters designed to measure ion content in water and wastewater using colorimetric analysis. The document details the principle of operation, display codes, and tips for accurate measurement.
The manual includes specific sections for the operation of the HI 93710 and HI 93724 models, listing their measurement ranges, required reagents, and step-by-step measurement procedures for parameters such as pH, free and total chlorine, and cyanuric acid. It also covers common specifications shared across the series, including environmental conditions and battery life.
| Light Source | Light Emitting Diode @ 555 nm |
|---|---|
| Battery Type/Life | 1 x 9 volt/40 hours |
| Auto-Shut off | After 10' of non-use |
| Dimensions | 180 x 83 x 46 mm |
| Weight | 290 g |
| pH Range (HI 93710) | 5.9 to 8.5 pH units |
| Free Chlorine Range (HI 93710) | 0.00 to 2.50 mg/L |
| Cyanuric Acid Range (HI 93724) | 0 to 80 mg/L |
The meters use colorimetric analysis based on the principle that specific compounds react to form a color, the intensity of which is proportional to the concentration of the substance.
The battery life is approximately 40 hours.
