Bamo Dissolved Oxygen Monitor BAMOPHAR 451

Dissolved Oxygen Monitor BAMOPHAR 451[/caption]

In association with the probe AQUAPLUS, BAMOPHAR 451 allows the user to continuously measures the oxygen content dissolved in the water. With this complete system, atmospheric pressure, temperature and water conductivity are taken into account to display a reliable and accurate measurement. BAMOPHAR is equipped with a color touch screen for the display of a multilingual menu friendly and intuitive.

The reading is easy for measurement, temperature and relay status. In order to facilitate its commissioning, a programming menu can simulate the measurement, acting on analogue outputs and thresholds. The measured value of dissolved oxygen and temperature can be continuously transmitted through the 4-20 mA outputs.

A complete system includes:

• 1 Monitor BAMOPHAR 451
• 1 probe AQUAPLUS
• 1 Probe holder for immersion, PVC, Ø 50 mm
• 1 Cable to connect the holder to the monitor

BAMOPHAR 451 is extremely versatile by use of various parameters for control and regulation on thresholds, temperature correction and alarms.

An extension terminal (wall, panel or DIN rail mounting):

• Allows a second measuring parameter (pH, flow-rate, conductivity, etc.) (Data from this blind unit are displayed on the main unit)
• Connected to main unit with 4-wire shielded cable (Cable length between both devices: max. 500 m)

Features

• Dissolved oxygen measurement
• Scales: 0.01 to 50 mg/l or 0 to 500 %
• 1 Input for AQUAPLUS probe
• 2 Analogue outputs 0/4-20mA
• 4 Relay outputs (Thresholds and alarm)
• OPTION: Extension terminal for 2nd measuring parameter

Application

BAMOPHAR 451 offers a reliable and accurate measurement of dissolved oxygen (DO) concentration in water treatment process:

• WWTP survey (e.g. aerated basin)
• Rivers and lakes
• Fish farming
