pH Meters
Bante221 Portable pH Meter
Professional portable pH meter with relative mV measurement modes, 1 to 5 points calibration, setup menu contains 10 options, accuracy 0.002 pH.
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.
? Automatic temperature compensation ensures accurate readings over the entire range.
? Calibration due alarm reminds user to calibrate the meter regularly.
ORP
? 1 point offset calibration allows adjusting the displayed value to a known standard.
? Relative and absolute millivolt modes ensure the reliable ORP measurements.
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 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.
? Multimode power scheme (batteries, power adapter, USB port) ensures the smooth operation
of the meter.
