WWD POOL 2-Way Pool & Spa Test Kit — Free Chlorine (OTO) and pH, Compact Carry Case

WWD POOL's 2-way test kit measures free chlorine (OTO/CL) and pH levels so you can quickly check pool or spa water balance.

Keep pool and spa water clear and safe by testing regularly with a compact, easy-to-use kit from WWD POOL. This two-parameter kit includes color reagents, a clear testing block with integrated color scales, two reagent bottles, and a protective carrying case. Results are fast and readable, helping you decide whether the water needs chlorine, pH adjustment, or further testing.

How do I use the WWD POOL 2-way test kit correctly?

Testing takes only a few minutes and needs no special tools. Fill the test tubes with sample water, add the recommended drops of solution, cap and shake, then compare the sample color to the built-in color keys on the testing block.

• Fill each tube to the marked fill line with pool or spa water.
• Add four drops of the chlorine reagent to one tube and four drops of the pH reagent to the other.
• Replace caps, invert gently to mix, and set tubes into the clear testing block.
• Match each tube’s color to the corresponding scale to read chlorine and pH values.

What readings will this kit give and what do they indicate?

The kit supplies free chlorine (using OTO reagent) and pH readings. Free chlorine indicates sanitizer level while pH shows water acidity or alkalinity; together they help you decide on balancing steps or additional treatment.

• Chlorine scale (OTO) shows free chlorine concentration for sanitizing action.
• pH scale determines whether water is acidic, neutral, or alkaline.
• Use both results to guide chlorine dosing or pH increaser/decreaser additions.
• Repeat tests after adjustments to confirm proper balance.

What comes in the box and how long does it stay accurate?

The kit includes two 1/2-ounce reagent bottles (chlorine and pH), a clear testing block with integrated color charts, a plastic test tube set, and a carrying case. Reagents have a shelf life; check the printed expiration date on the case and replace reagents once expired for reliable readings.

• One 1/2-ounce chlorine (OTO) solution bottle and one 1/2-ounce pH solution bottle.
• Clear view testing block with color scales and two plastic test tubes.
• Compact carrying case for storage and transport.
• Observe expiration date printed on the case to ensure accuracy.

How often should I test my pool or spa with this kit?

Frequency depends on bather load and weather: test at least weekly for routine maintenance, more often after heavy use, rain, or chemical adjustments. Frequent checks help prevent cloudy water and maintain comfortable conditions for swimmers.

• Weekly testing for typical residential pools and spas.
• Test after heavy swimmer use, storms, or visible cloudiness.
• Retest after adding any chemical adjustments to confirm balance.

Who is this for: The WWD POOL 2-way test kit is designed for homeowners, property managers, and spa technicians who want a compact, affordable way to monitor chlorine and pH. It’s ideal for anyone who prefers quick, visual results and a portable kit that fits in a maintenance closet or pool shed. For those needing broader water analysis (alkalinity, cyanuric acid, or bromine), consider supplementing this kit with additional test strips or a multi-parameter kit.
