Emphasis on High Accuracy? By Legaline Device Environment Influences Validation!
Temperature range 0° C to + 40° C Since 1996 the Legatest is used by the Inspection Bodies and Accredited Labors, according to EN ISO/IEC 17025, EN ISO/IEC 17020).
- Automatic calculation of measurement uncertainty.
- Correction or compensation of environment influences.
- System automatically calculated resultants acceptance criteria from Valves Standards.
- Trend (history) function.
Testing method by Legaline Valve test device and the L-plan as Conformity Assessment – Inspection Body is approved by:
- Bureau Veritas
- Slovenian Acreditation institute (based on ILAC MRA– International Laboratory Accreditation Cooperation)
