Description
BAMOPHAR 451 Bamo Dissolved Oxygen Monitor 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)
BAMOPHAR 451 Bamo Dissolved Oxygen Monitor 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
