Aquachek 7 way test
The AquaChek Pro 5-way test strips and AquaChek Silver 7-way test strips both feature a new 20ppm colour block for free chlorine.


The products now test for free chlorine at levels of 0, 0.5, 1, 3, 5, 10 and 20ppm, and AquaChek says the 20ppm colour block is the highest available on a pool and spa test strip product.

“The addition of the 20ppm colour block to AquaChek Pro and Silver was in response to the many requests by pool service professionals for a quick, reliable and accurate method for detecting high levels of chlorine, should water conditions warrant it,” says Joe Sweazy, technical sales and services manager for the company.
