   4) Selectable concentration units (ppm, mg/L, mol/L) and ionic valency

4. Other Features:

   1) Automatic temperature compensation ensures accurate readings over the entire range

   2) Auto-Read function senses and locks the measurement endpoint

   3) Calibration due alarm prompts user to calibrate the meter regularly

   4) Setup menu allows setting the number of calibration points, stability criteria, temperature unit, date and time, auto-power off, etc

   5) Reset function automatically resumes all settings back to the factory defaults

   6) Expanded memory stores or recalls up to 500 data sets

   7) USB communication interface for data transfer and timed interval readings
