CPHM920 Precision pH/mV/ORP/C/F Meter by Citizen Scale

CPHM92 Series meters includes models 920, 921, 922 it is a high accuracy meters used for measuring the pH and Oxidation-Reduction Potentital (ORP) of liquies.

Automatic Calibration

The meters is capable of calibrating up to 3 points using USA or NIST pH standard buffer. From Setup Menu, choose calibration and immerse pH electrode into calibration solution, press ENTER key and meter is automatically calibrated.

Automatic Electrode Slope Display

After calibration, the percentage slope of the electrode is displayed. According to the electrode indicator, you can decide whether the replace the pH electrode.

Save and Communication Interface

CPHM 92 Series have real-time date/clock stamps. The memory stores up to 99 discrete data sets. Press the SAVE key to store the current values and it automatically generates a serial number with the date and time. This data can then be sent to a computer via the USB port.

Fluid Resistant Housing and Swivel Electrode Holder

The integrated plastic housing and keypad is sealed to protect against accidental spills and splashes. The electrode holder arm is rapidly switched to both sides and swivels and articulates for convenient use and positioning.
