Temperature & High Limit Sensors

Temperature & High Limit Sensors

Welcome to the Temperature & Hi-Limit Sensors section of our store.

We stock a large range of sensors for spa control systems manufactured by Balboa, Gecko, Hydroquip & Sundance. Temperature sensors are a very important part of your spa's control system as they monitor the water temperature and tell the control system when & when not to turn the heater on, protecting you and the spa from overheating water conditions.

If you are having problems finding the correct sensor for your spa simply give us a call or contact us here.
