Clausen Instrument Company, Inc. offers our customers a full service repair department. We repair, service and calibrate most brands of equipment. When sending us repair work please fill out the Repair Request Form and ship it with the instrument. Please call or email us in advance to discuss your repair or parts needs.  We have an extensive parts inventory.  Our in-house facility has been keeping your equipment in the field since 1974.  It has always been the foundation of our business.  With full time trained technicians, an extensive parts inventory and the latest tools and calibration equipment, we can provide the best quality repairs with the shortest turn-around time possible.  We recommend a check-up and recalibration every 6 months for instruments in full-time use.  If an instrument is hit or dropped or exposed to excessive moisture (dry any external moisture with a  soft cloth, do not use a hair dryer), don’t hesitate, get it to us ASAP.   We absolutely recommend that you have your instruments checked-out BEFORE starting any job!
