HotSpring and Caldera spa sensors

We sell temperature sensors and Hi-Limit sensors and their spare parts that are compatible with HotSpring and Caldera hot tubs.

• A temperature sensor, as the name implies, is used to detect the water temperature, which is indicated on the spa's keypad.
• An overheating sensor (called "Hi-Limit") is a safety device programmed to activate when the water temperature exceeds 40°C, the maximum temperature on most spas.
