pHamp pH Preamplifier

The pHamp is a compact unity gain preamplifier designed to convert the high impedance signal of a pH electrode into a low impedance signal capable of travelling up to 1,000 feet over a coaxial cable.

This rugged preamplifier is encapsulated within an epoxy filled stainless steel enclosure and uses BNC-style input and output connections. Powered from a lithium battery, the expected life is a minimum of 5 years.
