Borin Stelth 2 Buried and Concrete Reference Electrodes

  Stationary Reference Electrodes for Underground and Concrete Minimum 20 year service life. 28 square inches of sensing surface area gives 9 to 35 times more surface areas than other electrodes. This makes electrode positioning less critical to achieve accurate readings. Will not dry out in desert dry soil, a condition that renders other electrodes ineffective. Cyclical variations in soil conditions, ranging from hydrated to dehydrated, will have an adverse effect on the Stelth 2 electrode. Will not be destroyed by absolute dry soil conditions. It will only lie dormant until moisture returns. Electric Mud™ backfill will keep Stelth 2 in a moisture environment which keeps it continuously active. Electrode may be taken out of service for extended periods of time and reintroduced into the system without affecting electrode accuracy or ability to reactivate; electrode will fire up in under 5 minutes. Technologically advanced chloride ion trap prevents chloride contamination of electrolyt
