The Pentair SL1DW is a factory-original inline thermometer that provides dependable water temperature monitoring for pool and spa plumbing systems. Its large 3-inch dial displays readings on a dual scale covering Fahrenheit (30-130 F) and Celsius (0-55 C), accommodating any measurement preference. The thermometer includes a 3.5-inch stem paired with a 1/2-inch MPT nylon well that threads directly into 1/2-inch tees for straightforward setup. All-stainless steel construction for the case, stem, and connection point is hermetically sealed to guard against moisture intrusion and environmental wear. A slim-profile stem and lightweight sensor element respond quickly to temperature shifts, enabling precise monitoring and effective thermal management of your aquatic system.
