Longest Life, Lowest Maintenance

Pfaudler Model 03, 04 and Ring electrodes complete the full spectrum of pH electrodes for applications that can not be measured with the model 18 and 40 electrodes. These electrodes feature the same measuring electrode as found in the model 18 and 40 probes plus they feature a conventional pressurized flowing reference electrode. The pressurized reference solution prevents any penetration of the process into the diaphragm insuring reference voltage stability, thus eliminating drift.

These electrodes are primarily used in processes with a lower pH range (as low as 0-4pH) and applications that do not have a relatively constant sodium ion concentration.

Since these Electrodes are calibrated with standard buffers they are suitable for vessels that produce many different processes.

The flange mounting 03 & 04 electrodes are available in various lengths (12" - 126") to meet all process needs. The ring electrode mounts directly in a (2" or 3") pipe providing an un-obstructive process mounting.

These electrodes are totally glass coated which includes the flange mounting. They have external reference electrolyte reservoirs for easy maintenance. A Teflon gasket completes the seal without any metal parts.
