The more sophisticated pH test paper strip indicates pH from 1 (bright red) to 14 (dark brown). Values in between can be read by comparing with a color chart that comes with the strips. All have (100) strips of test paper per vial.

Hydrion chlorine test paper provides a simple, reliable, and economical means to measure the concentration of free available chlorine in sanitizing solutions. With color matches at 10-50-100-200ppm, the test paper measures concentrations between 10-200ppm.Federal, state and local health regulations require users of chlorine-based sanitizer solutions to have appropriate test kits available to verify the strength of sanitizer solutions. Sanitizer solutions are essential in the food service industry to ensure that sanitizers are at the proper concentration specified by the individual manufacturer.

Chlorine tablets and granular chlorine are the two most commonly used forms of chlorine. These two forms of chlorine are classified as Cyanurates, which simply means they contain Cyanuric Acid as an ingredient. Cyanuric Acid is a chemical that protects chlorine from being destroyed by the sun. Since chlorine is so susceptible to the sun's ultraviolet rays, Cyanuric Acid is a necessary ingredient. Although chlorine tablets and granular chlorine contain some Cyanuric Acid as an ingredient, the amount contained is merely a trace. Therefore, chlorine users will have to add Cyanuric Acid periodically. Cyanuric Acid is typically packaged and sold as either "Conditioner" or "Stabilizer," depending on the manufacturer. The recommended ideal range for Cyanuric Acid is between 30-80 ppm. Poolmanual.com recommends a reading closer to 40 ppm as ideal. 40 ppm is high enough to prevent the sun from destroying chlorine's effectiveness. Since chlorine tablets and granular chlorine are CYANURATES, a trace amount of Cyanuric Acid is added to the water as chlorine is continually added to the pool. Eventually then, the Cyanuric Acid reading will eclipse 100 ppm (maximum that is accepted), which will cause your pool to hold too strong of a continual chlorine reading. There is no chemical to reduce Cyanuric Acid. It can only be reduced by either partially or completely draining the pool. It will take many years of adding chlorine tablets or granular chlorine to eclipse that 100-ppm reading. These strips test for the determination of cyanuric acid in swimming pools.

Product Description How Pure is Your Water? A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-4 can tell you your overall water purity level,which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-4 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-4 is a great tool for drinking water, water filtration and purification,hydroponics (test your nutrients), colloidal silver, aquariums, RO/DI systems, pools and spas, and more.
