Stelth 7 IR-Free Probes

• The Stelth 7 IR Free and Stelth 7 IR Free Rocket reference electrodes were developed to take IR-Free on-potential and off-potential readings of a structure without having to shut down or to turn off any interference systems such as your own system rectifier, other rectifiers in the area, electric trains and subways, electrical transmission lines, etc., while reading only the single worst potential that exists on that structure.
• The Stelth 7 IR Free and Stelth 7 IR Free Rocket reference electrodes have a minimum design life of 30 years and an indefinite shelf life.
• The Stelth 7 IR Free and Stelth 7 IR Free Rocket reference electrodes will maintain a stability of 5 millivolts with 20 mega ohms impedance over 30 years.
• The Stelth 7 IR Free and Stelth 7 IR Free Rocket reference electrodes will operate in all ranges of soil and water conditions, from desert dry soils to flood zones, swamps, sea and fresh water environments.
• Eliminates expensive interrupters. Eliminates the tedious procedure of synchronizing a series of interrupters.
• Allows you to take off-potential readings on rectifiers that have high amperage outputs which are beyond the handling capacity of the interrupters on the market today.
• This technology easily allows any remote monitoring and control system (process control system) to automate the IR Free on-potential and off-potential readings of a structure.
• On-potential and off-potential measurements can now be taken with a total disregard for any and all outside influences, such as your own rectifier, neighboring rectifiers, anode beds, electric transmission lines, trains and subways, steel in concrete, etcetera.
• Now, with the Stelth 7 and the Bullet^® Box IR Free interrupter you can read the current required to protect the holiday with the worst potential on your structure in the area being monitored.
• Can be reused and taken out of service as many times as desired.
• Shipping weight is only 3 pounds.
• Temperature range from -10° to 176°F (-23° to 80°C).
