Density Reference Standard Fluids

National Institute of Standards and Technology (NIST) approved kinematic viscosity reference standards for calibration and verification of all type of viscometers.

Categories: ,
  1. General Details

    National Institute of Standards and Technology (NIST) approved density reference standard fluids for calibration and verification of glass capillary viscometers, automated kinematic viscometers, rotational viscometers, falling ball viscometers, cup viscometers, tapered bearing simulator viscometers and flash point testers.

    Traceability

    All  density reference standards are traceable to a NIST calibration and prepared in ISO 9001-registered, A2LA ISO 17025 and Guide 34 accredited laboratories according to the ASTM D2162 standard.
