Calibration certificates for industrial thermoelements and Working Standards

Thermolab is the advanced laboratory, founded by Endress+Hauser Italy, which ensures a competent calibration of thermoelements and working standards.

 

Our Thermolab can issue SIT calibration certificates which are mutually accepted by EA (European cooperation for Accreditation).  
By issuing a SIT Calibration Certificate Thermolab ensures :

the validity of calibration methods (full compliance with EN45001 series of standards)
use of calibrated measuring equipment
traceability of measurements
a reliable quality system
reporting the results and the uncertainty of measurements

Material certification

 

Factory Calibration Certificate is a certification of calibration for industrial thermoelements. Calibrations are carried out in comparison with working standars traceable to national standards of International System of Units (SI).

TZC 105

 

SIT Calibration Certificate is a certification of calibration for industrial thermoelements and working standards issue by E+H Thermolab and mutally accepted by EA. Calibrations are carried out in comparison with Secondary Standards of International System of Units (SI) and all measurement procedures are according to EN45000 series.

TZC 101

 

Material Certification is a document issud on the basis of inspection and tests carried out in accordance with technical specifications of the order or the official regulations and the corrisponding technical rules. The tests shall be carried out on the products supplied or the products in the inspection unit, of which the consignment constitues a part.

The inspection unit is set by the product standard, the official regulations and the corresponding technical rules or by the order.

The Inspection certificate "3.1B" is issued by the department independent of the manufacturing department and validate by an authorised representative of the staff independent of the manufacturing department.

TZC 131B (Chemical analysis, sight and dimension control, mix-up test, if necessary with tagging certificate)

The Inspection certificate "3.1C" is issued and validate by an authorised representative of the purchaser, in accordance with the specification of the order.
