Serial No.
116260306
Asset ID: TL0010730
Equipment Condition:
 Satisfactory  Calibrated Repaired
Damaged Rejected Requires Spare Part
Environmental Conditions:
Temperature : 25 ± 4 °C
Relative Humidity : 50 ± 20 %RH
Calibration Method:
The Equipment with above description was calibrated as per internal Procedures Traceable to International
standards and Calibration Guidelines as per Manufacturer Requirements
The reported expanded uncertainty of measurement is stated as the standard uncertainty of measurement multiplied
by the coverage factor k = 2, which for a normal distribution corresponds to a coverage probability of approximately
95 %.
Traceability
The measurement results are traceable to the international system of units (SI) through national metrology
institutes (NIST USA) or accredited Scope of calibration laboratories. Details available below.
