As standard all our products come with a UKAS traceable calibration certificate. Meaning that all our reference equipment has been inspected, evaluated and calibrated by a UKAS accredited laboratory whose own apparatus is traceable to national or international standards. If a full UKAS certificate is required, we can provide a full UKAS certification through our association with the appropriate UKAS-accredited laboratories, speak to our technical sales team when you initially place the order.
