Figure 1: LaMotte Insta-Test 30 Free Chlorine and pH Analyzer Kit. This image displays the complete kit, including two blister packs of TesTabs (DPD 1 for Free Chlorine and Phenol Red for pH), a blue plastic case for storage, and a clear plastic comparator block with color charts for both Free Chlorine (CI DPD) and pH.
Setup
Preparation for Testing
- Ensure the comparator block is clean and dry. Rinse with the water to be tested before use.
- Gather the appropriate TesTabs for the desired test (DPD 1 for Free Chlorine, Phenol Red for pH).
- Collect a water sample from the area to be tested. For pools, collect water at elbow depth, away from return lines.
Operating Instructions
Free Chlorine Test Procedure
- Fill the left chamber of the comparator block to the "FILL" line with the water sample.
- Add one DPD 1 TesTab to the water sample in the left chamber. Do not touch the TesTab directly with your fingers.
- Cap the chamber and shake gently until the TesTab dissolves completely. A pink color will develop if free chlorine is present.
- Immediately compare the color in the chamber to the Free Chlorine (CI DPD) color standards on the comparator block. Read the result that most closely matches the sample color.
pH Test Procedure
- Fill the right chamber of the comparator block to the "FILL" line with the water sample.
- Add one Phenol Red TesTab to the water sample in the right chamber. Do not touch the TesTab directly with your fingers.
- Cap the chamber and shake gently until the TesTab dissolves completely. A color will develop indicating the pH level.
- Immediately compare the color in the chamber to the pH color standards on the comparator block. Read the result that most closely matches the sample color.
Note: For accurate results, perform tests immediately after collecting the water sample and read results promptly after TesTab dissolution.
Maintenance
Cleaning and Storage
- After each use, thoroughly rinse the comparator block with clean water and allow it to air dry.
- Store TesTabs in their original blister packs in a cool, dry place, away from direct sunlight and moisture.
- Keep the entire kit in its protective storage case when not in use.
Troubleshooting
Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Expired TesTabs, contaminated sample, improper technique, dirty comparator. | Check TesTab expiration date, collect fresh sample, review operating instructions, clean comparator. |
| No Color Change | No free chlorine/incorrect pH, TesTab not dissolved, expired TesTab. | Ensure TesTab is fully dissolved, check expiration, re-test with fresh TesTab. |
| Difficulty Matching Color | Lighting conditions, color blindness. | Perform test in natural daylight, seek assistance from another individual if necessary. |
