Dissolved Oxygen Meter, Portable, BEP-M820/BEP-M821
Description
DESCRIPTION
DESCRIPTION
•1 or 2 points calibration using the air-saturated water or zero oxygen solution
•Salinity and barometric pressure compensations eliminate the measurement error
•Automatic temperature compensation ensures accurate readings over the entire range
•Auto-Read function senses and locks the measurement endpoint
•Auto-Power Off effectively conserves battery life.
•Setup menu allows setting the number of calibration points, resolution, temperature unit, concentration unit, stability criteria, date and time, etc.
•Reset function automatically resumes all settings back to the factory defaults
•Expanded memory stores or recalls up to 500 data sets
•USB communication interface for data transfer or connecting a power adapter to meter
