The internal piston design ensures a tight seal with a minimum pressure drop

Engineered with high-grade copper alloy contacts and a precision-sensing disc

this is a passive conductivity probe and is generally compatible with most 24V or 120V AC conductivity-based liquid level controllers

ensuring a drop-in replacement without bracket modifications

Key Benefits for Contractors: Dual-Point Monitoring: Consolidates high and low pressure sensing into a single
