Multiparameter Meters
Bante903 Benchtop pH/Dissolved Oxygen Meter
High-precision benchtop pH dissolved oxygen meter provides accurate measurements of pH, ORP and dissolved oxygen, suitable for laboratory applications.
Features:
pH
• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
• Automatic electrode diagnosis shows the pH slope and zero offset.
ORP
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt modes ensure the reliable ORP measurements.
Dissolved Oxygen
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
• Salinity and barometric pressure compensations eliminate measurement errors. 
Other Features
• Automatic temperature compensation ensures accurate readings over the entire range.
• Auto-read function senses and locks the measurement endpoint.
• Calibration due alarm reminds user to calibrate the meter regularly.
• Setup menu allows setting the number of calibration points, stability criteria, temperature unit,
date and time, auto-power off, etc.
• Reset function automatically restores all settings to the factory defaults.
• Expanded memory stores or recalls up to 500 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.
