How do I know if I have a WaterGuru SENSE S1 or S2 device?

Mike Stueve

WaterGuru SENSE S1 was launched in 2020 and has continued to be sold on both waterguru.com and Amazon.com through 2023.

WaterGuru SENSE S2 was launched 5/25/23 on waterguru.com and includes a Float ring for use in Hot Tubs and Above Ground Pools.

If your WaterGuru SENSE did not come with a Float ring, you have a WaterGuru SENSE S1
