Hydrolevel EL1220 Probe Standard 1/2" NPT 2"-7/8"

The Hydrolevel EL1220 Probe Standard is a ceramic-based probe that is high quality and designed for use in low water cut-off and boiler control applications. It has a 1/2" NPT connection size and inside dimension of 2-7/8", and provides reliable water level sensing in steam and hot water boilers. This probe is made of durable ceramic the corrosion and high temperatures pose no threat to the system's longevity. It stops the firing of dry and reduces boiler efficiency and maintenance costs by the accurate water level. This is an ideal component for application in HVAC systems for the safe operation and increased overall performance of the boiler, therefore it is essential for the proper operation of the boiler.
