WeAQUA DoubleCheck Water Hardness Test Kit 200 Strips with Sample Cup – Hard Water Testing Strips (0-25 gpg / 0-425 ppm)
$8.48
- 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.
