Permanent Ceramic Reference Electrodes underground and concrete encased applications (space-age porous ceramic)

·       Size:  1.5" dia. x 6" long space-age ceramic tube with yellow protective caps.

·       Lead Wire:  50' of #14 RHH-RHW yellow.

·       Stability:  +5 millivolts with 3.0 microamp load.

·       Temperature Range:  32° F to 135° F.

Features:

·       Available in three sizes:

o   15sq. in 0.83" dia. x 6" long

o   28sq. in 1.5" dia. x 6" long

o   33sq. in 1.75" dia. x 6" long

·       Greater surface area than other standard electrodes allows greater accuracy readings.

·       Electrode does not dry out in arid soils.  Moisture content change in soil has no effect on electrode.

·       Electrode has an infinite shelf life.  Minimum service life is 20 years.

·       Copper-Copper and Zinc-Zinc sulfate electrodes are equipped with advanced chloride ion trap to prevent chloride contamination.

·       All electrodes are side-reading.

·       All electrodes are color-coded for electrode type determination.
