The SCRIBE Digital Half Cell
The SCRIBE is used for assessing the probability of corrosion in steel reinforcing bars
Corrosion of the re-bars is an electro-chemical process which involves anodic ( corroding ) and cathodic ( passive ) areas of the metal.
By measuring concrete-surface electrical potentials relative to a standard reference electrode, areas where corrosion is present can be determined.
The SCRIBE is equipped with a detachable silver/silver chloride electrode, and measurements are automatically converted to copper/copper sulphate equivalent potentials and displayed on the digital meter.
Satisfies BS 1881:Part 201 and ASTM C876.
The SCRIBE comes in an aluminium carrying case with an extensible probe holder for remote operation.
Input impedance 33Megohms
Display 3½ digit plus sign via 12.5mm LCD
Range/resolution +1999mV, +1mV
