Non-polarizing electrode VNP

VEGA LLC produces non-polarizing lead-chloride electrodes. A one-piece housing without components and a durable silicone wire ensure the reliability, strength and durability of the structure. We can make it in any quantity.

Testing of VNP electrodes

Results of parallel test of VNP electrodes: two pairs of electrodes installed into two identical parallel electric lines. The recordings are compared to calculate the noise level of the electrodes.
