DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup - Hard Water Testing Strips (0-25 gpg / 0-425 ppm)

Features

• DOUBLECHECK - Each strip has two identical color pads. If the color pad colors differ after testing, it indicates that the test may not be reliable it should be performed again.
• SAMPLE CUP INCLUDED - Ensure the most accurate water hardness test results by using the included sample cup and filling the test water to the marked level.
• 200 STRIPS @ $0.04 EACH - The most strips available in the box with the lowest cost per test.
• ⁠INDIVIDUALLY WRAPPTED - For the longest shelf life possible the strips are packed in foils of 50. This prevents unused strips from going bad due to too much contact with air.
• DUAL TOP & BOTTOM DESICCANTS – Strips stay fresh for longer with two desiccants, one in the cap and one in the bottom of the bottle, to prevent moisture buildup.
