This is the instruction manual for Hanna HI 38015 Chloride Tester. This instrument is used to measure chloride concentration in water and wastewater.
This document is an instruction manual for the Hanna Instruments HI 38015 Chloride Extended Range Test Kit. The kit allows users to determine chloride levels in water and wastewater using a silver nitrate titration method with potassium chromate as an indicator. It includes various reagents, syringes, pipettes, and a demineralizer bottle necessary for the analysis.
| Range (High) | 5000 to 100000 mg/L (ppm) Cl- |
|---|---|
| Range (Low) | 500 to 10000 mg/L (ppm) Cl- |
| Smallest Increment | 100 mg/L for High Range; 1000 mg/L for Low Range |
| Analysis Method | Silver nitrate titration |
| Sample Size (High Range) | 0.25 ml |
| Sample Size (Low Range) | 2.5 ml |
| Number of Tests | 100 |
The chloride level is determined by a silver nitrate titration using potassium chromate as an indicator.
The color change from yellow to brick-red determines the end point.
Read the milliliters of titration solution and multiply by 100,000.
Interferences include bromide, iodide, cyanide, sulfide, orthophosphate above 250 ppm, polyphosphate above 25 ppm, and iron above 10 ppm.
