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.
