Sutro 6-Way OTO Test Kit

The 6-Way OTO Test Kit is a standard diagnostic tool used by pool and spa owners to measure vital water chemistry levels, including chlorine, bromine, pH, acid demand, and total alkalinity. This specific kit is often associated with the brand Sutro, which emerged as a leader in smart water monitoring technology.

Sutro was founded in San Francisco, California, with the mission of simplifying pool maintenance through hardware and chemical analysis. While the brand is known for its high-tech floating monitors, it utilizes traditional reagents and testing standards produced in the United States to ensure accuracy for residential and commercial water safety.
