Phosphor Bronze Rolling Springs

An alternative to Stainless Steel Rolling Springs, the Phosphor Bronze Rolling Springs can be up to three times lighter than their diametric equivalent.

They also have less capacitance, making it easier for the instrument to consistently deliver the set voltage to the probe while testing. This is particularly important when using the Elcometer 280, especially at high voltages at the upper end of the range (in other words closer to 30kV), or when testing large diameter pipes.

Each spring is supplied with an easy-release coupling piece, allowing users to quickly connect and disconnect the rolling spring from stanchions, pillars, etc.

Please note that rolling springs are not supplied with a spring holder. Please order the appropriate rolling spring holder separately.
