Industrial Solid-state

Reference Electrodes

Model: GD Series

Properties and Specifications:

The model GD solid-state reference electrodes are designed as whole closed body and with polymer as basic substance. With special materials consisting the electro-conductive membrane, the fashion of liquid junction is essentially different from original flowing ones. Durability, higher resistance to temperature, pressure, corrosion, abrasion, scaling and convenience for use and maintenance are all the advantages of this type of electrodes.

Main specifications:

Potential vs. SCE (25℃) ：-45±5 mV (GD-6)/-56±5 mV (GD-4)

Working temperature: ≤80℃(GD-6) ≤130℃(GD-4)

Working Pressure: ≤10 MPa

pH range: 0～12 pH

Impedance: ≤15 KΩ(GD-6)，100kΩ(GD-4)

Fields of Application:

GD series industrial solid-state reference electrodes can be used in on-line determination of pH or ORP in conjunction with the corresponding sensor electrodes (such as glass electrodes, antimony electrodes, platinum electrodes etc.) GD series reference electrodes are suitable for medium of low ionic intensity (such as high purity water), organic medium (such as kerosene) and glutinous medium (such as cosmetics). The electrodes also can be used in high temperature and pressure systems, such as fermenting tanks for antibiotics, terrestrial heat water, high-temperature corrosion system, deep-sea determination and oil fields exploration etc.

This type of products was approved of Chinese Patent of Invention and was rewarded with gold medal at Beijing International Fair 1991.
