Model 820 portable dissolved oxygen meter use a polarographic electrode to measures dissolved oxygen in water, it can display the oxygen level as % saturation from 0 to 200% or concentration from 0 to 20ppm (mg/L).
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, Bante820 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
Bante820 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.
Meter Included:
- DO Probe(Made in US),
- Membrane Cap
- Electrolyte Solution
