Measurement Parameters:

PH-320: pH, mV, relative mV, ion concentration, temperature

PH-321: lon concentration, mV, temperature

Features:

pH

*1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.

*Automatic electrode diagnosis shows the pH slope and offset.

ORP

*1 point offset calibration allows adjusting the displayed value to a known standard.

*Relative and absolute millivolt modes ensure the reliable ORP measurements. 

Ion Concentration

*2 to 5 points calibration, including the 8 concentration points can be selected.

*Direct concentration readout simplifies the measurement process.

*Automatic electrode diagnosis shows the calibration points and slopes.

*Selectable concentration units (ppm, mg/L, mol/L, mmol/L) and ionic valency.

General Features:

*Automatic temperature compensation ensures accurate readings over the entire range

*Auto-Read function senses and locks the measurement endpoint.

*Calibration due alarm prompts user to calibrate the meter regularly.

*Auto-Power Off effectively conserves battery life.

*Setup menu allows setting the 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 PC.

*Multi-mode power scheme (batteries, power adapter and USB port) Ensures that using the meter smoothly.
