Kruger Instruments - Calibration Services

Our standard calibration and adjustment service for a differential pressure gauge against an NIST traceable reference. This service includes anything and everything required to adjust a gauge and re-calibrate it to within tolerances. That said, the gauge has to be "in working order," and our standard calibration service, although including adjustment, does not include repair or replacement of any pieces. If repair is required, we can provide an assessment and a quote to repair then gauge then calibrate after repairs.

Our service is tailored to customers who have differential pressure gauges working in the backflow prevention testing fields. Therefore, we do not have equipment to calibrate gauges that are more accurate than +/- 0.2 PSID. If you have any questions about this, let us know before shipment. A general list of acceptable gauges include the Kruger Instruments TK-2, TK-1, Midwest 830, 835, 845, Apollo 40-200-TKU, Danfoss TK-1, Watts TK-9A, TKDR, TK99E, Wilkins TG-3, TG-5, among others. Notably some electronic gauges and the Midwest 837 are more accurate than 0.2 and would require more accurate equipment to calibrate.

In order to keep our service cost effective, we do not include any shipping. We can calibrate gauges at any of our classes with Kruger's Training Academy - just bring the gauge and we can do it on site - or you can mail the package to " Kruger's Training Academy, 200 Greene St., Unit 2305, Jersey City, NJ 07302 " but if mailing it, we suggest that you get insurance due to possible damage in shipping (taking to a course prevents loss or damage during shipping). Also we don't include shipping in the pricing, so you can either include a return label in the box, or we can calibrate the gauge and take a credit card for the return shipping. Calibration produces a report that is submitted to the relevant jurisdiction, included in the box with the gauge upon return either on site or in the mail.
