Benchtop pH meter suitable for different types of samples.
It has a backlit LCD display that simultaneously shows pH / mV / RmV and Temperature readings, as well as date, time, cell status and calibration points.
Simple operation through guided on-screen menus with key indicators for the user.
Software in Spanish.
AUTO-READ function.
Stable reading indicator.
Up to 5 pH calibration points with recognition of USA / NIST and DIN standards.
Stores up to 2000 readings, associated with date and time, in its non-volatile memory.
It includes a newly designed support arm that makes it easier to place and hold the electrodes inside the samples.
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).
With the calibration edit function, you can correct the errors of a calibration without recalibrating again.
IP54 splash-proof protection.
