Abstract
A multifunctional detection test paper includes a base and a plurality of test modules attached to the base. The base includes a base layer and a hydrophobic layer coated thereon, wherein the hydrophobic layer has a plurality of test zones spaced apart from each other. The test modules are provided on the test zones of the hydrophobic layer respectively to separate the test modules from the base layer, wherein each of the test modules includes a detection substance being configured to detect one of pH value, total alkalinity, cyanuric acid, total chlorine, bromine, free chlorine and water hardness when the test modules are immersed into water.
