Product Description

Most spas and hot tubs leave the showroom with an ozone generator.  Ozone generators need to be maintained and replaced, just like the other critical components such as heater, pump and filters.

Ozone is in charge of the spa water sanitation.  More powerful than chlorine and bromine, ozone disinfects the water and leaves you with crystal clear water that looks, smells, and feels great. 

The average lifespan of a spa ozonator is 3 years.  So, if your ozonator is 3 years or older, it may be time to replace.  If you ask yourself, "Why is the chemistry so hard to balance?  It use to be so easy!"  Yep.  That's your ozonator, begging to be replaced.

In 2009, DEL Ozone brought these Ozone Test Kits to the market.  Designed for Spa Technicians, we take the 10-pack and break them down and repackage them into singles to meet your needs (buy 1, 2, 3, etc).  If you order ONE, you will get one single glass test (not a 10-pack).

Do you need an ozone test?  Not necessarily.  Most spa ozonators need to be replaced every 2-3 years, and some strut their stuff up to 5 years (like DEL's new SpaEclipse NEXT GENERATION, MCD-50, MCD-250, SO, HO and T3).  If your spa is over five years old, don't waste time or money testing the ozone generator, just replace it.

TIP:  In DEL Ozone's video below, the ozone test is performed at the ozone generator's hose barb (intake nipple).  That is the safest place to test because there is no sticky, yellow nitric acid (which can irritate your skin).  You CAN test it here, but know this:  if your spa ozonator has aged enough, the hose barb will snap off!  If your hose barb looks brittle, test instead at the ozone check valve by removing check valve and testing in its place...where the check valve was.

We highly recommend you buy an Ozone Supply Check Valve now.  In most cases, the check valve is stuck and needs to be cut out (can't remove and replace).  Check valves should be replaced every year.

If you need help finding a qualified spa technician to test and/or replace your spa ozonator, we can help.  We know lots of professionals across the U.S. that can help you out.  Email us at help@loveyourhottub.com

  1. Not sure this works 1 Star Review

    I purchased one of these test kits along with a brand new ozone generator. After correctly installing the generator, I followed the tester instructions and the test indicated about 1/3 of the tube content changed colors within 30 seconds. According to the test instructions, that indicates that I need a new generator.
    Guess I’ll just to have to take it in faith that my brand new ozone generator is actually working.
