ASTM, ground- and precision mercury thermometers, for mineral oil testing

Instruments for standardised material testing methods e.g. mineral oil testing etc.

  • Stabilisation of the thermometer zero point by careful artificial ageing (molecular constant)
  • The solid-stem types have the graduation indestructibly diffused into the glass surface and are acid and base resistant
  • The enclosed-scale versions each have a prismatic capillary that makes for better reading
  • Measurement accuracy within tolerances specified by AFNOR, ANSI, ASTM, BS, DIN, IP, ISO, PTB, S.T.P.T.C. or other standardisation institutes
    On request, also available with internationally recognised DKD certificate (ILAC)

Ludwig Schneider Thermometers

Ludwig Schneider is one of the world’s leading manufacturers of precision measuring instruments for temperature and density.
Based on these experiences its subsidiary company Ludwig Schneider Messtechnik GmbH (LSM) offers calibration services
for temperature measurements for more than 15 years.
Since 2005 LSM has been the first private-sector company in Germany with DKD accreditation for density measurements of
hydrometers.
International customers of the chemical, pharmaceutical, mineral oil/refinery, food processing industries and oceanography
are using the LSM calibration services.

PTB accreditation

Ludwig Schneider Messtechnik is accredited under registration
number DKD-K-06701 by the Accreditation Body „Deutsche
Kalibrierdienst“ (DKD) and fully complies with the requirements
of ISO/IEC 17025. United under the International Laboratory Accreditation Cooperation (ILAC), 52 nations at present have contractually agreed to mutually accept the calibration results of the signatories’ accredited calibration laboratories according to ISO/IEC 17025.

Range of services

  • Fixed-point calibration of interpolation thermometers
  • Comparative measurements of resistance thermometers, thermocouples,
    liquid-in-glass thermometers, temperature indicators, temperature block calibrators
  • Adjustment of digital/analog measured data acquisition systems
  • Calculation of specific constants on the basis of ITS-90 deviation functions,
    Van Dusen equations, polynomial functions
  • Documentation of calibration results: DKD calibration certificates, manufacturers test certificates, conformity statements, compliance with QM codes and standards (DIN, ASTM, BS,IE, etc)
