Ph Meters

A pH meter consists of three essential parts: a pH measuring electrode, a reference electrode and a high input impedance meter. The reference electrode has a known, constant and stable potential.

The pH electrode can be considered as a battery, with a voltage that varies according to the pH of the measured solution. The pH-determining electrode is a hydrogen ion sensitive glass bulb, with a millivolt output that varies according to alterations in the relative concentration of hydrogen ions inside and outside the bulb. The output of the reference electrode does not change with the activity of hydrogen ions.  The pH electrode has a very high internal resistance, which makes it difficult to measure voltage variation with pH. Therefore, the impedance of the pH meter input and the dispersion resistances are important factors.

Types of PH meters a Laboratory may need

Portable

• BNC connector is capable of connecting the different types of pH electrodes.
• 1 to 3 points calibration with auto-buffer recognition.
• Manual temperature compensation allows adjusting the temperature value.
• Auto-Read function senses and locks the measurement endpoint.
• Auto-Power Off effectively conserves battery life.
• Setup menu allows setting the pH buffer group, number of calibration points, temperature
unit, etc.
• Reset function automatically resumes all settings back to the factory defaults.

Table PH meters

  • The economy benchtop pH meter is equipped with a white backlit LCD display.
  • Automatic electrode slope display helps user decide if he wants to change the sensor.
  • Automatic temperature compensation ensures accurate measurement, result.
  • 2-point pushbutton calibration with buffer auto-recognition.

Accessories

  • PH electrode
  • The temperature probe (only for the PHS-3BW and PH-210 meter)
  • PH buffer bags (pH4.01 / 7.00 / 10.01)
