Laboratory/General Use Plastic and Glass ORP Electrodes
Parts covered by this product data sheet include:
Model # SG500C-ORP, SG500CD-ORP, S500C-ORP, S500CD-ORP, S550C-ORP, S550CD-ORP, S555C-ORP, S555C-ORP-AU, S555CD-ORP, S350CD-ORP, S450CD-ORP
Most ORP measurements can be made with single junction reference electrodes. However, materials such as heavy metals, proteins and sulfides can precipitate at the junction. Double junction designs use a buffering salt such as KNO3 in the lower chamber contacting the sample, and prevent these reactions. For separate reference half cells, see LabSpecs.
