pH:
1 to 5 points push-button calibration with auto-buffer recognition
Selectable pH buffer group (USA / NIST / DIN) or using the custom calibration solutions
Automatic electrode diagnosis with pH slope and offset display.
Automatic Temperature Compensation provides accurate reading over the entire range.
Calibration Due Reminder prompts 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.
GENERAL:
Stability indicator shows when a measurement is recognized as stable.
Auto-Hold feature senses and locks the measurement endpoint.
Setup menu allows setting the 10 parameters, including the number of calibration points,
resolution, stability criteria, temperature unit, auto-power off, etc.
Reset feature automatically resumes all settings back to factory default options.
Expanded memory stores and recalls up to 500 data sets.
Stored readings can be transferred into the computer by USB communication interface.
Multi-mode power scheme ( batteries, power adapter or USB port) ensures that use the
