Chlorine Test Kit

The pH & Chlorine Test Kit will help you keep your hot tub water crystal clear and balanced. This test kit provides a specific test for free Chlorine and pH levels using the Titration (drops) method. This kit includes two reagents for accurate testing; an OTO 1/2 oz for the Free Chlorine level, and a Phenol Red 1/2 oz for pH.
 
To properly titrate (apply drops) while testing, reagent bottles need to be fully vertical during titration to ensure that the correct drop is produced.
