Gould-Bass Company offers both in house and on site repair, maintenance and calibration services. Our calibration lab offers a quick turnaround (usually within 7 days) for calibration and certification of gauges, indicators, shunt kits, and timers. Items are returned via UPS Blue Label (2-Day service) at no extra charge. Certifications can be provided with quarterly, semiannual or annual expiration dates depending upon the specifications to which your facility complies. Be sure to specify which schedule your instrument requires. All certifications are NIST traceable and we provide both before and after readings on all of our certifications. For ease in submitting your instrument for calibration, please complete a Calibration Request Form and include a copy with your unit.
