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 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.
