Operating Instructions
Follow these steps for accurate measurement of chlorine and pH levels:
- Rinse Test Block: Before each use, rinse the test block thoroughly with the water to be tested.
- Fill Test Block: Dip the test block into the pool, spa, or hot tub water to be tested, ensuring both chambers are filled to the marked line. Avoid touching the inside of the chambers.
- Add Reagents:
- For Chlorine (Cl2) measurement (right chamber): Add one DPD1 tablet. Do not touch the tablet with your fingers.
- For pH measurement (left chamber): Add one Phenol Red pH tablet. Do not touch the tablet with your fingers.
- Dissolve Tablets: Place the lid on the test block and gently shake until the tablets are completely dissolved and the color has developed. This usually takes a few seconds.
- Read Results: Hold the test block against a white background in good natural light. Compare the color in each chamber with the corresponding color scale on the test block. Read the value that most closely matches the developed color.
- Chlorine (Cl2) Range: 0.1 - 6.0 mg/l
- pH Range: 6.8 - 8.2

Maintenance
Proper maintenance ensures the longevity and accuracy of your Pooltester SP 610:
- Cleaning: After each use, thoroughly rinse the test block with clean tap water. Do not use abrasive cleaners or brushes, as these can scratch the plastic and affect readings.
- Drying: Allow the test block to air dry completely before storing it in the case.
- Storage: Store the Pooltester and reagent tablets in a cool, dry place, away from direct sunlight and extreme temperatures. Keep tablets in their original blister packaging until ready for use to protect them from moisture and contamination.
- Reagent Expiry: Check the expiry date on the reagent tablet packaging. Expired tablets may give inaccurate results.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate readings | Expired reagents, contaminated test block, improper tablet dissolution, incorrect water sample. | Use fresh reagents. Clean test block thoroughly. Ensure tablets fully dissolve. Collect water sample from appropriate depth away from jets. |
| Tablets not dissolving | Insufficient shaking, old tablets. | Shake the test block more vigorously. Check tablet expiry date and replace if necessary. |
| Color does not develop | Missing tablet, incorrect tablet type, expired tablet. | Ensure a tablet is added to each chamber. Verify correct tablet type (DPD1 for chlorine, Phenol Red for pH). Use fresh tablets. |
