ORP Meters
Bante221 Portable ORP Meter
Professional portable ORP meter, 1 point calibration, setup menu contains 9 options, accuracy: 0.2 mV.
ORP Mode:
• Professional portable ORP meter is equipped with a backlit LCD display.
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt modes ensure the reliable ORP measurements.
pH Mode:
• 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.
Other Features:
• Auto-read function senses and locks the measurement endpoint.
• Auto-power off effectively conserves battery life.
• Setup menu allows setting the number of calibration points, resolution, stability criteria, 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 for data transfer or connecting a power adapter to the meter.
