(supplied).
Failure to thoroughly clean the electrodes between tests may contaminate
subsequent tests and result in inaccurate readings.
The Elcometer 130 measurement electrodes are gold plated to prevent corrosion
and oxidisation, prolonging the life and accuracy of the gauge. They should be
cleaned using pure water and the sensor wipes supplied. DO NOT use abrasive
materials as this will damage the electrodes.
