Dissolved Oxygen Meters
A181 Laboratory Dissolved Oxygen Meter
High-precision laboratory dissolved oxygen meter, suitable for measuring dissolved oxygen concentration and saturation, setup menu includes 15 options, accuracy 0.2 mg/L.
Features:
? 7-inch TFT display clearly shows measurement values, parameters and operation guidance.
? 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
? Salinity and barometric pressure compensations eliminate measurement errors.
? Auto-read function senses and locks the measurement endpoint.
? Timed interval measurement sends data to memory or a printer.
? Limit alarm automatically alerts when measurements exceed the specified range.
? Calibration due alarm reminds user to calibrate the meter regularly.
? Calibration log shows the date, time, calibration points, etc.
? Password protection prevents unauthorized calibration and settings.
? Expanded memory stores or recalls up to 1000 data sets.
? USB communication interface enables easy data transfer to a PC.
? DAS software is capable of receiving data, recording measurements at specified intervals,
exporting data to Excel.
