Benchtop pH and conductivity meter suitable for all types of samples.
It has a backlit LCD display that shows readings of:
pH / mV / RmV or Conductivity / TDS / Salinity
Simple operation through guided on-screen menus with key indicators for the user.
Software in Spanish.
5 pH calibration points with automatic recognition.
AUTO-READ function.
Stable reading indicator.
Selection of 2 or 4 cell conductivity probe.
Stores up to 2000 readings, associated with date and time, in its non-volatile memory.
Easy download of data to PC via USB port or RS232 port with the analysis software.
Possibility of incorporating a rod stirrer (code 096019, sold separately).
It works with a 220V mains adapter, but can also be powered with batteries (4 alkaline AA type).
IP54 splash-proof protection.
