pH sensor amplifier

Description

Use: The pH probe consists in an electrode sensitive to pH. The electrode produces a voltage which is proportional to the hydrogen ions concentration of a given solution.

N.B.: The operation of this probe is difficult at a pH level above 13 since the scarcity of hydrogen ions will produce a weak signal.

Technical specifications

Sensor (not included)    balle_verte.gif (257 bytes) GEL Electrode
Operational range    balle_verte.gif (257 bytes) 0 to 13 pH
