The meter is used for measuring the pH and millivolt of samples. Accuracy: 0.01pH. Features: Stability indicator automatically shows current measurement status. Auto-Hold function freezes stable reading for easy viewing and recording. Automatic electrode diagnosis shows offset and electrode slope. Reset feature automatically resumes parameters back to factory default options. pH Mode (For PH-221\/320): 1 to 5 points push-button calibration with auto-buffer recognition. Automatic electrode slope display helps user decide whether to replace sensor. Automatic Temperature Compensation provides accurate measured values. Calibration Due Reminder prompts you to calibrate the meter regularly. ORP Mode(For PH-221\/320): 1 point offset calibration allows adjusting the displayed value to a known standard. Relative and absolute mV measurement modes provide accurate ORP readings.<br \/>\nLead Time: Standard Lead time: 3 &#8211; 4 working days. Imports: 4 &#8211; 6 Weeks.
