## Description

Water Hardness Test Strips

## 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.
