Solid State Instruments (SSI)
Solid State Instruments provides the best pulse isolation relays and pulse metering in the industry to protect electrical equipment from transient voltage spikes. We also offer a large selection of specialty pulse products used for providing additional outputs, long distance transmission, “noise” conditioning, and totalizer metering.
In 2009, Solid State Instruments eliminated the use of mercury-wetted relays in every product.
By moving forward with this green initiative, our products all contain solid state relays. Our latest line of pulse metering totalizers continues our green tradition, replaces all previous totalizers, and offers our clients more options.
