2012 New Portable Oxygen Meter 820/821 Series
Introduction:
820/821 Series Portable Dissolved Oxygen Meter
This Series meters use 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).
Details:
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.
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 limits oxygen content, this series meters can compensates salinity and barometric pressure after manual input coefficients.
Multi-Measurement Units:
The meters can choose the various units for different countries. Example: mg/L vs. ppm; kPa vs. mmHg. Degrees.C vs. F, and so on.
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:
The meters displays helpful messages like an on-screen manual for easy operation of this meter and choosing of the various functions and options.
Save And Communication Interface:
This series all have real-time date / clock stamps, The memory stores up to 48 discrete data sets. Press the SAVE to
store the current measured values and it automatically generates a serial number with the date and time. This data can
then be sent to a computer via the USB port.
