CPHM930 Precision pH/ORP/Ion/C/F Meter by Citizen Scale

CPHM 930 is an accuracy multi-parameter meter that is used to measuring the pH, Oxidation-Reduction Potential (ORP) and ion concentration of liquids , it widely used in various water quality research, quality control and industrial applications.

Multi-point Push-button Calibration

The meter has multi-point calibration mode. From setup menu, choose calibration and immerse electrode into indicated solution, press ENTER key and meter is automatically calibrated.

Viewing of Electrode Slope

After calibration, the percentage slope of the electrode is displayed before the meter returns to measurement mode. Per the slope value, user decides whether to change the electrode.

Ion Concentration Measurement

CPHM 930 has 13 types of Ion measurement to choose. From the screen menu select the desired ion type and press ENTER. The pX value is display, Use the ENTER key again to switch between pX, ppm and mg/L values.
