Drinking water test strips 25 pack

This pack contains 25 test strips designed to check drinking water quality. Each strip measures free chlorine, total chlorine, nitrite, nitrate, total hardness and pH in a single dip. The product suits homeowners, landlords and small businesses that need routine water monitoring without laboratory equipment.

Check parameters before ordering

Verify that the six measured parameters match the contaminants you need to track. The strips cover 0 to 10 ppm free chlorine, 0 to 10 ppm total chlorine, 0 to 10 ppm nitrite, 0 to 50 ppm nitrate, 0 to 400 ppm total hardness and a pH range of 4 to 10 with 1.0 pH resolution. If your application requires bacteria, lead, pesticide or other specific analyte detection, these strips will not provide that data.

Simple use with minimal overhead

Testing requires dipping a strip and comparing colours to the supplied chart; no power, reagents or calibration instruments are involved. Each strip is five inches long and one quarter inch wide for easy handling. The 25-test quantity supports repeated checks over time. The process produces no waste heat, noise or electrical load, making it suitable for quiet environments and portable use.
