Calibration Services

Calibration Laboratory

We are having Unique and Comprehensive Calibration Service Facilities for Primary in-house facility for force calibration. We have state of art in-house/onsite calibration facility in Vadodara for Force, Temperature and Pressure Parameter. We have complete set of equipments, knowledge & skills to provide laboratory as well as onsite calibration facility.

We proud to say that Hemshell Services is a Sole Calibration Laboratory in India which is using the imported Gold Standard Interface, Ametek-Jofra makes Reference standards. Reference Standard from Hemshell are calibrated from the NPL and International Laboratory Accreditation Cooperation (ILAC) laboratory.

Our standards have traceability to national / international standards, and calibrated from NPL and Ametek Calibration Instruments traceable to the ILAC & DANAK in Denmark through recognized international laboratories. So the customers can be assured as to the accuracy of their instrument. Calibration, which is a process of comparison, is therefore associated with a level of uncertainty. Our reports indicate the uncertainty associated with the measurements. Our team works, keeping the ‘Clients requirements’ as the focus.
