The REMOTE DISPLAY is connected to its own 12-pole connector. The 16-pole Signal Con-
nector is free for access to all signal inputs and outputs. The analyser must be ordered as
BMT 965 AQ/RD in order to operate together with a REMOTE DISPLAY.
For further description of the functions and properties of the OZONE-IN-WATER SENSOR
BMT 965 AQ refer to the main part of the manual.
