DPD Chlorine and pH Pool Water Test Kit
Our DPD Chlorine and pH Pool Water Test Kit is designed for routine monitoring of free chlorine and pH levels in swimming pools, saltwater pools, spas, and hot tubs.
Using DPD 1 reagent tablets for free chlorine measurement and Phenol Red tablets for pH analysis, this colorimetric testing solution helps pool owners, maintenance technicians, and water treatment professionals evaluate essential water chemistry parameters.
The reagents produce visible color changes that can be interpreted using a compatible color comparator or photometer. This provides a practical solution for regular pool water monitoring without complex laboratory procedures.
Key Features
- Two Essential Water Tests: Measures free chlorine using DPD 1 reagent and pH using Phenol Red indicator tablets.
- Colorimetric Testing: Produces a measurable color reaction for straightforward water analysis.
- Suitable for Saltwater Pools: Helps monitor free chlorine generated by saltwater chlorine generators.
- Convenient Reagent Tablets: Premeasured tablet formulations simplify routine testing.
- Protective Blister Packaging: Individually sealed tablet cavities help protect reagents from moisture and contamination.
- Professional Applications: Suitable for residential swimming pools, commercial pool maintenance, spas, and water treatment services.
- OEM and Private Label Support: Custom labeling, packaging, and wholesale supply solutions available upon request.
What Does the DPD Pool Test Kit Measure?
DPD 1 – Free Chlorine Measurement
DPD stands for N,N-Diethyl-p-phenylenediamine, a widely used chemical reagent for chlorine analysis.
DPD 1 tablets react with free chlorine in a water sample to produce a pink color. Within the specified testing range, the intensity of the color corresponds to the free chlorine concentration.
Free chlorine is the portion of chlorine available for water disinfection. Monitoring its concentration helps pool operators maintain appropriate sanitizer levels.
Phenol Red – pH Measurement
Phenol Red is a chemical indicator used to measure the acidity or alkalinity of water.
When dissolved in a water sample, Phenol Red produces a color change ranging from yellow through orange and red toward purple, depending on the pH level and the indicator’s measurement range.
Maintaining appropriate pH levels is important for swimmer comfort, equipment protection, and effective chlorine disinfection.
DPD 1 vs. Phenol Red Tablets
| Parameter | DPD 1 Tablets | Phenol Red Tablets |
|---|---|---|
| Measurement | Free chlorine | pH level |
| Testing principle | Colorimetric oxidation reaction | Acid-base indicator reaction |
| Color change | Colorless to pink/magenta | Yellow to red/purple |
| Typical application | Chlorine monitoring | Water pH monitoring |
| Compatible equipment | Suitable comparator or photometer | Suitable comparator or photometer |
How to Use DPD and Phenol Red Test Tablets
- Collect the sample: Fill a clean testing cell with the required volume of pool water.
- Select the reagent: Use DPD 1 for free chlorine measurement or Phenol Red for pH measurement.
- Add the tablet: Remove the appropriate reagent tablet from its blister packaging and place it into the sample.
- Dissolve the reagent: Mix according to the manufacturer’s testing instructions.
- Read the result: Compare the resulting color with a compatible reference scale or measure it using an appropriate photometer.
- Record the measurement: Record the free chlorine concentration or pH value and adjust pool water treatment as necessary.
Important: Use separate samples for chlorine and pH testing. Sample volume, reaction time, and measurement range depend on the specific reagent formulation and testing equipment.
Applications
- Saltwater Swimming Pools: Monitor free chlorine generated by saltwater chlorination systems and maintain appropriate pH levels.
- Residential Swimming Pools: Perform routine water chemistry checks.
- Commercial Swimming Pools: Support scheduled chlorine and pH monitoring by pool maintenance professionals.
- Spas and Hot Tubs: Check chlorine-treated spa water and pH balance.
- Pool Maintenance Companies: Conduct on-site water quality testing during service visits.
- Water Treatment Professionals: Perform routine colorimetric chlorine and pH analysis with compatible equipment.
Why Test Chlorine and pH in Saltwater Pools?
Saltwater pools use a saltwater chlorine generator to produce chlorine from dissolved salt. Although these pools use salt, they still rely on chlorine for disinfection.
Regular DPD chlorine testing helps verify that the generator is maintaining an appropriate free chlorine concentration.
Testing pH is equally important because pool water pH influences chlorine effectiveness, swimmer comfort, and the condition of pool equipment.
Note: DPD 1 and Phenol Red tablets measure free chlorine and pH, respectively. They do not measure salt concentration. A separate salt or sodium chloride test is required to determine pool salinity.

Frequently Asked Questions
What is DPD 1 used for in swimming pool testing?
DPD 1 is used to measure free chlorine concentration in swimming pool and spa water. It produces a pink color reaction that can be measured using a compatible comparator or photometer.
Can this DPD test be used in saltwater pools?
Yes. Saltwater pools generate chlorine through electrolysis, and DPD 1 testing can be used to monitor the resulting free chlorine concentration.
What is the difference between DPD 1 and Phenol Red?
DPD 1 measures free chlorine, while Phenol Red measures pH. Both are commonly used together in pool water testing systems.
Does DPD 1 measure total chlorine?
No. DPD 1 is intended for free chlorine measurement. Total chlorine requires a suitable additional reagent, such as DPD 3 used after DPD 1, or a compatible total chlorine formulation.
Can I customize the packaging for my own brand?
