The pH Input is in effect a voltage input with a very high impedance (1 x 10¹²ohms) that enables a pH sensor to be directly connected to the Squirrel data logger.

• Care should be exercised when multiple sensors are used within the same solution, e.g. when calibrating due to possible cross coupling.
• Visit www.thermorussell.com for more information on pH sensors.
