pH Meters

Bante221 Portable pH Meter

Professional portable pH meter with relative mV measurement modes, 1 to 5 points calibration, setup menu contains 9 options, accuracy: 0.002 pH.

pH Mode:
• Professional portable pH 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.
• Automatic temperature compensation ensures accurate readings over the entire range.
• Calibration due alarm reminds the user to calibrate the meter regularly.

Portable pH Meter

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.

Portable pH Meter

Other Features:
• Auto-read function senses and locks the measurement endpoint.
• Auto-power off effectively conserves battery life.
• Setup menu allows setting the pH buffer set, number of calibration points, resolution, 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.
