* Portable Dissolved Oxygen Meter
* 1 or 2 Points Calibration
* Manual Salinity and Barometric Pressure Compensation




Automatic Calibration:
The meter can be calibrated at one or two points - in air (100%) and/or with a zero oxygen solution, easy and quick calibration ensures accurate reading.


Auto-Calibration Recognition:
During calibration, if the calibration condition does not match the meter's requirement, an ERROR message is displayed.


Automatic Temperature Compensation:
The DO probe with a globular shape temperature sensor, it can provides automatic temperature compensation to ensure accurate measuring value.


Salinity and Barometric Pressure Compensation:
Salt dissolved in solution will be limits oxygen content, Bante821 meter is capable of compensates the salinity and barometric pressure after manual input coefficients.


Multi-measurement Units:
The meter can shows various temperature and concentration units to meet users requirements. For example: mg/L and ppm, kPa and mmHg, Celsius and Fahrenheit.


Hold Function:
To keep the latest measurement on the display, after taking a reading press the HOLD key and the measurement remains on the display, You can easily view and record data.


Power Monitor:
During using, The CPU continuously monitors and displays the battery level, When the battery is running out of power, The battery icon will disappear from the LCD.


Message Indicator:
Selon821 Portable Dissolved Oxygen Meter meter has message indicator, it can shows many helpful messages like an on-screen manual for easy operation.


Communication Interface and Data Store:
The meter has real-time date/clock stamps, the memory stores up to 48 data sets. Press the SAVE key to store the current

measured values and it automatically generates a serial number with time. All of stored data can then be sent to a computer via the USB port.
