Frequently asked questions

ISO9000: Focuses on guidance and tools that products and services must consistently meet for quality to be consistently improved.

To comply with ISO9000 one requires ISO17025 calibrated equipment, and internal laboratory and external laboratory services.

ISO17025: ISI/IEC 17025 General requirements for the competence of testing and calibration laboratories. ISO17025 focuses more specifically on requirements for technical competence and the implementation of quality systems aimed at improving the ability to consistently produce valid test results.

Uncertainty of measurement determines its accuracy. ISO 17025 requires all uncertainties to be added to come up with the combined measurement uncertainty.

Expanded measurement uncertainty (I.e., Expanded Uncertainty): Combined standard measurement uncertainty and a factor larger than one.

Measurement uncertainty is usually expressed as an expanded uncertainty U = k*uc, where k is the coverage factor and uc the combined standard uncertainty.

Expanded uncertainty with a coverage factor k of 2 which provided an interval with a level of confidence of approximately 95%.

Accuracy is the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard.

Precision is the refinement in measurement, calculation, or specification, especially as represented by the number of digits given.

This product is covered by Sigma Care! Which gives you a standard 25 cycle, the 3-month warranty is included. This does not cover breakage – strictly workmanship and technical performance. Should a sensor go out or a production defect arise, these are covered for 6 months.

Yes, Sigma Care extends the warranty to 12 months and is available on an extended basis.

Recalibration is up to the customer. SIGMA recommends a 12-month interval until drift is established and documented. Your process requirements should override any recommendations as we do not have any input on your processes.
