The probe allows, following to insertion and locking into the socket of a medical gas terminal unit, the withdrawal of a given gas from the distribution system.

They are characterized by the interface point between probe and socket complying with standard EN ISO 5359.

Safety and performances features comply with EN ISO 9170-1.

In order to prevent dangerous misconnections, dimensional features of connection points are different for each gas.

Gas symbol is punched on the gas-specific probe.

Devices are entirely brass—made, surfaces chrome plating reduces contamination at a level much smaller than those specified by applicable standards and increase wear resistance of mostly stressed areas.
