Our refrigerator and freezer thermometers are designed to help protect your valuable samples. Each Traceable® unit is individually serialized, calibrated and certified. An individually serialized Traceable® Calibration Certificate provides assurance that an independent auditor has checked the methods, procedures, testing, technique, and record-keeping practices of the calibration testing laboratory. The American Association for Laboratory Accreditation (A2LA) is widely recognized internationally through its participation in the International Laboratory Accreditation Cooperation Mutual Recognition Agreement (ILAC MRA). There is no need to have the units calibrated locally before use as all European governing bodies fully accept and recognize the Traceable® certificate of calibration.
