pH Meters
Bante900P Portable pH/Conductivity/Dissolved Oxygen Meter
Multiparameter portable pH meter, suitable for measuring pH, oxidation reduction potential, ion concentration, conductivity, total dissolved solids, salinity, resistivity and dissolved oxygen.
pH Mode:
• Multiparameter water quality meter is equipped with a backlit LCD display.
• 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 Mode:
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt modes ensure the reliable ORP measurements.
Ion Concentration Mode:
• 2 to 5 points calibration, including the selection of 8 concentration points.
• Automatic electrode diagnosis shows the calibration points and slopes.
• Direct ion concentration readout simplifies the measurement process.
• Selectable concentration units (ppm, mg/L, mol/L) and ionic valency.
Conductivity/TDS/Salinity/Resistivity Modes:
• 1 to 5 points calibration with automatic recognition for conductivity standards.
• Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear and
pure water compensations, seawater and practical salinity measurement modes.
Dissolved Oxygen Mode:
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
• Salinity and barometric pressure compensations eliminate the 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 the user to calibrate the meter regularly.
• Auto-power off effectively conserves battery life.
• Setup menu allows setting the number of calibration points, stability criteria, temperature unit,
date and time, etc.
• Reset function automatically resumes all settings back to the factory defaults.
• Expanded memory stores or recalls up to 500 data sets.
• USB communication interface is easy to transfer data to a PC.
• Multi-mode power scheme (batteries, power adapter, USB port) ensures the smooth operation
of the meter.
