Information on the calibration of newly purchased equipment and what it means to you.
Calibration and its certification comes in varying forms on new equipment and in this section, we will break it down into the three areas that we use to classify calibration state at the point of purchase.
Manufacturers Calibration Certificate
This is a calibration certificate offered by the manufacturer supplied with the tester. This is also known as an end-of-line certificate or manufacturer’s certificate. These certificates vary depending on the manufacturer and product. They will not have your company's name on them and don’t always show proven test results.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes complete with the manufacturer's calibration certificate. Please be aware that these certificates are generic and may also be time-lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.Manufacturers Certificate of Conformity
A manufacturer's certificate of conformity is not a calibration certificate. It is merely a statement that the equipment has been produced to operate within its intended application, it has no traceable certificate or constitutes any defined results for accuracy before leaving the manufacturing process.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.Personalised traceable calibration certificate from isswww
This is a calibration certificate created by us at ISS. This certificate is fully traceable to national and international standards. The certificate will show your company's details, tester information, proven test results and the equipment used to carry out the test. Nearly 90% of all calibrations we do are done in-house in one of our many fully equipped laboratories. You can add this service to your order on the product page before you checkout.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
We are on occasion able to offer FREE calibration on certain products at their point of sale (newly purchased equipment only) please look out for the following badge on the product's page to take advantage of this free offer.
