Glycol (Secondary Refrigerant) Tester

This handy rink tool removes the guess work from knowing the glycol solution "freeze protection temperature" rating. With the Glycol Tester you will know the exact freeze protection temperature of the glycol (ethylene or propylene) solution in your rink refrigeration pipe grid system and be able to protect your rink system from freeze damage. If you are going to do the job, be certain to have the right tools!
