Dissolved Oxygen Meters

A181 Laboratory Dissolved Oxygen Meter

High-precision laboratory dissolved oxygen meter contains measurement modes for dissolved oxygen concentration and % saturation, setup menu includes 15 options, accuracy: 0.2 mg/L.

Features:
• High-precision laboratory dissolved oxygen meter is equipped with a 7 inch TFT display.
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
• Salinity and barometric pressure compensations eliminate the measurement errors.
• Auto-read function senses and locks the measurement endpoint.
• Timed interval readings send the measurement data to a PC or printer.

Laboratory Dissolved Oxygen Meter

• Limit Alarm automatically alerts when reading exceeds the specified range.
• Calibration due alarm reminds the user to calibrate the meter regularly.
• Calibration log shows the date, time, calibration points, etc.
• Password protection prevents the unauthorized calibration and settings.
• Expanded memory stores or recalls up to 1000 data sets.
• Reset function automatically resumes all settings back to the factory defaults.
