Industrial Test Systems 481348 Copper 3 in 1 Pool Check | Made in USA | 3 Parameter Pool Test Strips | Copper, pH, & Total Alkalinity | Easy Match Colors | Lowest Copper Detection Levels

Direct from the USA Manufacturer Made in USA POOLCHECK COPPER 3 IN 1 CONTAINS 1 BOTTLE OF 50 TESTS MEASURING THE TOTAL ALKALINITY, COPPER, AND PH WITHIN A WATER SAMPLE. With 3 tests combined into one strip, testing is super easy and efficient. No confusing testing with the new Pool Check COPPER 3 in 1. Just dip and read results in seconds. Test for Total Alkalinity, Copper, and pH all at the same time.Using our patented aperture design, Copper test strips allow the aqueous solution to pass back-and-forth through the impregnated chemical membrane. This unique design allows for the lowest sensitivity possible on a test strip. Coupled with this design is another unique feature, they contain 1/100th the amount of chemical compared to most commonly used test strips. PATENTED aperture (window) technology is more sensitive and more accurate than traditional test strips. More color blocks result in better accuracy. The pH indicator provides easy color matching for (YELLOW/GREEN/BLUE VS ORANGE/RED)improved accuracy and precision. 5 second dip time with motion allows lower detection levels and even color development NO COLOR BLEEDING EASY TO READ COLORS MADE IN THE USA

• EASY TO USE: Each bottle contains 50 TEST STRIPS with a single dip and read test strip procedure the product ideal for detection of COPPER, ph, and TOTAL ALKALINITY in swimming pool water.
• LOWEST DETECTION LEVELS ON A STRIP: Copper: 0, 0.2, 0.4, 0.7, 1, 2 ppm (mg/L); pH: 6.0, 6.4, 6.8, 7.2, 7.6, 8.2, 9.0 pH; Total Alkalinity: 0, 40, 80, 120, 180, 240, 360 ppm (mg/L)
• FASTER & EASIER THAN LIQUID TESTING KITS - Strips are faster and simpler than liquid testing kits, with accuracy as good or better. Color coding makes them easy to read, and they work equally well with chlorine or bromine present in water.
• ACCURATE AND RELIABLE: Components are tested by Quality Control personnel at each step and are rejected if they are outside of specifications. Standards are prepared using calibrated equipment, and concentrations are confirmed by recognized reference methods
• MADE IN THE USA FOR MAXIMUM ACCURACY - Test strips made overseas can be inaccurate, hard to read due to bleeding colors, fall apart, or do not even work. Instead choose quality with a leading American manufacturer of high-grade water testing products.
