• As of March 2017, HDI’s RMA form has been updated to obtain HDI serial numbers (gauge head and pressure transducer) and return shipping address per our ISO Quality Management System procedures to improve shipping and invoicing efficiency.

    IMPORTANT NOTE: If there are any fields other than HDI serial numbers, which are unknown while filling in the online form, please enter “N/A” which refers to Not Applicable.

  • Inspection Fee
    HDI’s standard inspection fee is $150.00 per gauge. All other additional repair costs will be included in the final quote after receiving and inspecting the gauge here at HDI Houston.

  • Warranty
    Each product or part returned to HDI which is under warranty (less than 1 year from original order date of delivery) will be inspected, repaired and shipped back to the customer at HDI’s return freight forwarding expense.
