INSTRUCTION MANUAL
1.0 GENERAL INFORMATION
The AquaMetrix Model 2200D Dissolved oxygen analyzer is a versatile industrial microprocessor
based instrument. Outputs are programmed through the menu with push buttons on the face of the
instrument. Calibration is also accomplished through the front panel menu. The instrument must be
used in conjunction with the AquaMetrix Model P91 dissolved oxygen sensor.
The instrument provides non-isolated 0-5 Vdc, 0-1 mA and isolated 4-20 mA analog outputs. The
analog outputs may be programmed to represent any segment of the measuring scale.
A membrane perforation alarm is provided which gives early warning of a membrane failure.
The instrument can also be used to take a temperature reading and one of the non-isolated analog
outputs can be used to give a continuous temperature signal.
The integrity of the system is ensured with a watch-dog timer and system alarm. A password
feature protects the stored values.
The instrument is housed in a NEMA 4X enclosure. The standard unit is provided with mounting
hardware for surface mount applications. Both panel and pipe mount kits can be ordered
separately.
