Bench Top pH Meter pH Meter Lab & Scientific Equipments


pH Mode:
  • 1 to 5 points push-button calibration with auto-buffer recognition.
  • Selectable pH buffer options or using the custom calibration solutions.
  • Automatic electrode slope display helps user decide whether to replace sensor.
ORP Mode:
  • 1 point offset calibration allows adjusting the displayed value to a known standard.
  • Relative and absolute mV measurement modes provide accurate ORP readings.
Ion Concentration Mode (For PH-930):
  • 2 to 5 points calibration providing the 8 concentration points can be selected.
  • Automatically recognize ion electrodes, does not need to specify the type of ion.
  • Selectable multiple concentration units include the ppm, mg/L and mol/L.
Others Features:
  • Auto-Hold function freezes stable reading for easy viewing and recording.
  • Automatic electrode diagnosis shows offset and electrode slope.
  • Expanded memory stores and recalls up to 500 readings.
  • Built-in real-time clock stamps stored data to meet GLP standard.
Accessories:
  • PH electrode  
  • Temperature probe 
  • PH buffer pouches (pH4.01/7.00/10.01)
  • USB cable    
  • DC5V power adapter
