PICO+ pH Meter

PICO+ pH Meter

This bench-top pH meter is an ideal help in every laboratory for routine or R&D level measurement. This very handy instrument measures pH, mV and has 40- point data memory storage.

Instrument has two operating modes - (a) Standard mode (b) GLP mode : 40 data readings can be stored, printed & scanned on display. For GLP mode, additional entries of sample name & ID number can be stored. The optional Data logging function enables user to store; 24 data points consisting of pH, temperature & time readings. For example as required in kinetic study or in any chemical reaction. Time intervals from 1min. to 1Hr. in steps of 1min. are available. User entries of pH limit values make the data more defined & informative.
