Boke821 portable meter uses polarographic electrode to measures dissolved oxygen in water, it can shows the oxygen level as % saturation from 0 to 200% or concentration from 0 to 20mg/L.

Automatic Calibration:

The meters 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.

Salinity and Barometric Pressure Compensation:

Salt dissolved in solution will be limits oxygen content, Boke821 DO meter is capable of compensates the salinity and barometric pressure after manual input coefficients.

Multi-Measurement Units:

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

Automatic Temperature Compensation:

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

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, the user can easily view and record data.

Power Monitor:

During using, The power chip will continuously monitors the battery level, When the battery is running out of power, The battery icon will disappear from the screen.

Message Indicator:

Boke821 meter has message indicator, it can shows many helpful messages like an on-screen manual for easy operation. 

Communication Interface and Data Store:

The meters have real-time date/clock stamps, the memory stores upto 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, DO Membrane Kit, DO Electrolyte Solution, Battery.

Optional Accessory: Carrying Case.
