ISO-9000 Certified Facility

Continuity of wire!

Continuity of wire insulation!

Resistance of lead wire and sensing elementconnection (has to be a dead short)!

Internal resistance of reference electrode!

Calibration of Reference Electrodes are done at the

final state of assembly at 25Celsius!

Final test is for response time from activation to

stable reading without Hysteresis!

EC/DIN-50925 IR Free Probe

Developed with the cooperation of

European Governments by the largest

Gas Distribution & Pipeline Company in Europe . . .

and is now a DIN Standard

Ruhr Gas


46/114

EC/DIN-50925 IR Free Probe Reads Average potential of pipeline!

Reads Current Required to protect Worst Holiday!

Compatible Remote Monitoring & Control Systems!

Reads the ON & OFFPotentials of the Worst Conditionon your pipeline!


47/114

EC/DIN-50925 IR Free Probe Eliminates expensive interrupters & the difficult

task of synchronizing them.

Allows you to take IR Free Off Potential readings

on High Amperage Rectifiers without interruptingor turning rectifier off.

IR FreeOn & Off Potential readings can takenwith total disregard for outside influences such as:

Other Pipelines, Your Own Rectifier,Subways,Electrical Trains, Electrical TransmissionLines, Anode Beds, et cetera.

Reference Electrode Designs

manufactured...

are affected by conditions that will alterthe performance or destroy your

reference electrode

Here are a several

Causes of Malfunction and Failure!!!

Take the Plastic Bag OFF before installation!

102/114

Temperature..

Can alter the accuracy & completelyshut down a reference electrodes

Upper Limit = 176 F (80 C)

Lower limit = -10 F (-23 C)

Environment


103/114

Environment..Can determine the accuracy of any reference

electrodes

Zinc-Zinc Sulfate Zn-ZnSO4

MUST be in a non-chloride environment

Either inSoil or Water

Copper-Copper Sulfate Cu-CuSO4or

WHY


104/114

WHY..

Because the chlorides alter

the chemistry of the copper sulfate

and prevent the necessary

ion exchangebetween the

coppersensing elementand the environment

Chl id


105/114

Chlorides..Kill more reference electrodes than any

other single influence

1000 PPM(parts per million)

will KILL any reference electrode

NOW


106/114

NOW..

Silver-Silver Chloride Ag-AgCIis a different story.

To achieve a proper ion exchange

You need between

10,000 and 27,000 ppmof chlorides with 19,000 ppm

being ideal, which is seawater
