The Jacks Magic Professional Test Kit provides consistent and highly
accurate test readings. The Professional Test Kit has been designed to
give pool professionals the accurate answers they need to test swimming
pool water and solve problems. To be successful with Jack’s Magic
products and systems, the swimming pool professional must have the tools
to accurately monitor pool water chemistry under “real world”
conditions. This kit utilizes tablets, which do not suffer from the same
degradation problems as do liquid reagents.
