We have always strived to offer our customers the best products possible and a large part of that goal is the ability to ensure that those products are both highly accurate and extremely dependable. Our instrument calibration and testing services allow us to validate each instrument for this type of reliability.

With our onsite calibration laboratory we are able to check an instrument at several different points using reference standards that are each independently certified and NIST traceable. We offer low-cost, single and multiple point checks at predetermined levels and we can fully customize the calibration service to each customer’s specific needs.

We test each device to the manufacturers’ accuracy specifications and tag them with the calibration standards and instrument details. These tags, attached to every instrument and its matching certificate, also show the service dates and when the equipment needs to be recertified.

Our highly trained and knowledgeable calibration technicians take the utmost care in testing each instrument. We expect them to deliver high quality and fast calibration services. They maintain an average turnaround of 2-3 days, with many calibrations shipping the next day!

Listed below is a summary of the features and the calibration services we offer for each product type. If you don’t see what you are looking for, let us know and we will be happy to create a plan that fits your needs.
