Abstract: A gas distributor for a rebreather, the gas distributor being configured for connection with an inhale hose and with an exhale hose with a mouthpiece in between, wherein the gas distributor comprises a gas distributor housing, an inhale chamber at the gas distributor housing and comprising a first inhale port for connection with an inhale counterlung or with a scrubber, a second inhale port for connection with the inhale hose, and a gas supply valve for supplying gas on demand, an exhale chamber at the gas distributor housing and comprising a first exhale port for connection with an exhale counterlung or with a scrubber, a second exhale port for connection with the exhale hose, and an overpressure valve for opening in an event of overpressure, and a switch arranged at the gas distributor housing and configured for being switchable between an open circuit mode and a closed circuit mode.

Abstract: A sensor cassette insertable into an analysis module for carrying out electrochemical measurement processes in sample fluids, including a sensor carrier which is essentially planar and carries electrochemical sensor elements for determining chemical and/or physical parameters of the sample fluids. The sensor elements are connected to conductor tracks formed on the sensor carrier. A cover part is arranged on the sensor carrier, in which at least one groove-shaped measuring channel that is intended for the flow of the sample fluid and opens towards the sensor carrier is formed, which measuring channel is connected to at least one electrochemical sensor element and is fluidly connected to at least one fluid connector arranged on the side facing away from the sensor carrier. The cover part is a two-component injection molded part having a hard component and a soft, component. The measuring channel is formed in the soft component over its entire length.

Abstract: A tank pressure transmitter with integrated breathing gas analyzer and associated methods are provided. The tank pressure transmitter can include a gas sensor which detects a constituent of a breathing gas. The transmitter is operable to compile a constituent reading from the constituent detected, and communicate this constituent reading wirelessly to a dive computer.

Abstract: The invention relates to a method for operating a rebreather, wherein oxygen is metered to the breathing gas as a function of a signal of at least one oxygen sensor (11). The oxygen sensor (11) is checked automatically by rinsing it with a gas having a known oxygen concentration. The safety of the system is improved in that the check is triggered automatically.
