Introduction of Portable Precision Dissolved Oxygen Meter 820
Toption 820/821 series meters use polarographic electrod to measure dissolved oxygen in water, it can display the oxygen level as % saturation from 0 to 200% or concentration from 0 to 20 ppm (mg/L).
Automatic Calibration of Portable Precision Dissolved Oxygen Meter 820:
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.
Auto-Calibration Recognition of Portable Precision Dissolved Oxygen Meter 820
During calibration ,if the calibration condition does not match the meter requirement ,an ERROR message is displayed!
Salinity and Barometric Pressure Compensation of Portable Precision Dissolved Oxygen Meter 820:
Salt dissolved in solution will be limits oxygen content, 8 Series meter is capable of compensates the salinity and barometric pressure after manual input coefficients.
Multi-Measurement Units of Portable Precision Dissolved Oxygen Meter 820 :
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 providesautomatic temperature compensation to ensure accurate measuring value.
Hold Function:
To keep the latest measurement on the display, after taking a reading pressthe HOLD key and the measurement remains on the display, the user caneasily 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 LCD.
Message Indicator:
the meters display helpful messages like an on-screen for easy operation of this meter and choosing of the various functions and options!
Save and communication interface:
The meter 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.
