A Thru Wall Thermowell is a small fitting that goes through your spa shell to help measure the temperature of your water. Inserted in the thermowell is a temperature sensor probe that connects to a Topside Command Center or a Spa Controller. This is a dry thermowell that fits a 3/8 inch temperature sensor probe, and keeps it dry.
SpaGuts P/N: 50-150-0044
Thru Wall Thermowells are a more precise way of measuring the temperature of the water in the spa than measuring the water temperature flowing through a plumbing fitting or a heater. Keep in mind that SpaGuts CS-Series and CY-Series temperature sensor probes must not be in direct water contact. This dry thermowell keeps the temperature sensor probe dry.
Dimensions (Approx): 3 inches long x 1-3/4 inches lip diameter. Requires a 1-1/8 inch round hole cut out for installation.
This item includes the drywell, securing nut, wall gasket, and split rubber grommet. NOTE that the color of the drywell may vary upon availability for shipment.
