Dissolved Oxygen Meters
A180 Laboratory DO/BOD/OUR/SOUR Meter
High-precision laboratory dissolved oxygen meter contains measurement modes for DO, BOD, OUR and SOUR, 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 measurement errors.
• Selectable testing time and beginning/ending dissolved oxygen are used to calculate OUR
(oxygen uptake rate) and SOUR (specific oxygen uptake rate).
• Automatic temperature compensation ensures accurate readings over the entire range.
• Auto-read function senses and locks the measurement endpoint.
• Timed interval readings send measurement data to a PC or 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.
• Reset function automatically restores all settings to the factory defaults.
