Spare Parts and Accessories

The STs Series is durable and designed to last many years with proper handling, but accidents do happen and you should be prepared.  We always recommend a replacement electrode in case of damage.  For critical applications, an additional STs Series device should be ordered to ensure that a replacement is available for any part in the event of damage.

Spare Parts and Accessories Price List


All orders of $500 or more receive free UPS Carbon-Neutral Ground shipping in the continental United States.  Your order will be shipped within 3-5 business days (unless otherwise noted) after payment has been received.  All customers may use their own shipping account and provide pHionics with the shipping label at time of purchase if that option proves cheaper.
