  • Direct replacements for GLI differential electrodes
  • Built-in preamplifier eliminates high-impedance wiring problems
  • Large reference reservoir extends time between preventive maintenance
The differential pH and ORP electrodes are ideal for industrial applications. Differential measurement technology minimizes ground loop interferences that can affect standard electrodes. In addition, a built-in pre-amplifier allows cable extensions up to 300 feet. Replaceable heavy-duty quad junction salt bridges and refillable reference solution extend the life of the sensor in severe applications, reducing the cost of ownership.

Electrodes have 1-1⁄2" NPT(M) threadson both ends for in-line or submersible mounting. A 300 Ω NTC temperature sensor allows the electrodes to be used as direct replacements for existing GLI electrodes.
