Durafet III Model 7777 pH Electrode

Honeywell's 7777 Style Series of electrode mountings enables a user to interface Durafet III pH electrodes to a process by either submersing the electrode or mounting it into a ¾ " threaded connection.
Durafet III pH electrodes use a non-glass, ISFET (Ion Sensitive Field Effect Transistor) technology for the pH sensor.
This solid-state ISFET technology eliminates the conventional fragile glass pH sensor and provides fast, accurate and dependable pH measurement in the most demanding industrial applications.

Typical applications include wastewater influent / effluent, neutralization, cooling towers and process pH measurement.

Uses ISFET (Ion Sensitive Field Effect Transistor) technology for exceptionally fast response.
Virtually unbreakable, truly solid state.
Vario Pin quick disconnect, IP68 waterproof cable for easy electrode installation/replacement
"No epoxy" packaging design for greater reliability
Reference junction frit and gel are replaceable.
Low impedance pH signal.
One electrode for entire pH and temperature ranges.
Retro fittable to existing pH instrumentation.

FM-approved intrinsically safe for Class I, Division 1, Group A, B, C, D areas with APT 2000/Direct Line transmitters and barriers. Rugged combination electrodes with fast-responding integral automatic temperature compensator.
Moulded, chemically-resistant Ryton body.
Suitable for in-line and submersion applications; may be mounted in any position.
Large reference electrode volume uses a true gel fill that maintains high viscosity with temperature.
Cap Adapter cable options for mounting to APT series analysers.
Direct Line remote cable options for mounting to DL421 Direct Line modules.
Other cable options to mount to UDA 2182 Analyser and older Honeywell instruments and preamps.
