pressure sensor for measuring higher pressures can be connected via
the AUX socket.
The analyzer is specifically not intended as a safety device or personal
protective equipment.
The analyzer should not be used as a warning device to warn people
against the presence of harmful gases.
The analyzer must be used according to instructions for the intended
