Romalon 42002-0024S Stack Flue Sensor - 2 Pack for Pentair MasterTemp & Sta-Rite Max-E-Therm

Keep pool and spa heater performance steady with Romalon 42002-0024S Stack Flue Sensor

This 2-pack of flue sensors is designed to sit at the exhaust elbow of compatible pool and spa heaters, where a reliable temperature reading helps maintain safe and efficient operation. The sensors are built to handle a broad range of temperatures, from chilly outdoor nights to warmer operating conditions, giving you peace of mind during seasonal changes. Rather than relying on a single component, the two-pack setup provides ready replacements, helping you minimize downtime if one sensor wears or fails over time.

Romalon emphasizes durability. The sensors are fashioned from stainless steel to resist corrosion in humid pool areas, and they undergo careful manufacture and testing to withstand regular use. This focus on sturdy construction can contribute to a longer service life in real-world settings, where heat, humidity, and routine maintenance test components. When installation is needed, following basic safety steps helps protect you and your equipment, such as powering down the system and using gloves during replacement.
