Does PDI recalibrate Parallel Seismic System’s Wilcoxon Hydrophone?

PDI recommends that clients send in the Wilcoxon Hydrophone unit for recalibration. It is not, however, required. PDI provides NIST-traceable (National Institute of Standards and Technology) calibration services for Hydrophone recalibrations. PDI offers recalibration with a certificate for $155 each. The client receives a standard One Year Calibration certificate, which details the used equipment and procedure. Note: Values reported are as found and as left, no adjustments are made. After receipt, the lead time is approximately 6 weeks.
