The calibration certificates are generated at the end of the manufacturing process at the factory. The factory calibration certificate provides traceability back to United States National Institute of Standards and Technology (NIST). However the NIST certificate is not recognized in Australia. In order to fill this gap, Data Logger Store uses equipment calibrated by NATA accredited laboratories as primary standards and is therefore traceable to the National Standard of Measurement. Each certificate indicates the date and conditions of calibration. These certificates provide the documentation needed to satisfy most requirements in Australia and New Zealand. To obtain a calibration certificate for your new data logger simply order at the time of purchase indicating whether you require a NIST or Traceability to National standards of measurement certificate. If you need to re- calibrate your existing data logger, simply complete the Calibration Request form and submit it to the Data Logger Store. Alternatively, you may contact the data logger store by email or phone
