Robust stainless steel leak detection probe, designed for the separate detection of conductive liquids (e.g. water, glycol, …) and non-conductive liquids (e.g. fuel, oil, …). This probe is designed to operate on its own, without other alarm control panels: it is equipped with two switching contacts (for leaks of conductive and non-conductive liquid), each with a potential-free, normally open and normally closed contact. A green, orange or red LED on the probe lights up to indicate the type of leak. This probe is perfectly suited as an autonomous detection for technical rooms, wells or rooms with fuel tanks. We also offer customization for detection in pipes, wireless detection in wells, etc.
