PH-321 Portable Ion Meter

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 ion 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.
