Calibration Standards
Manufactured in accordance with ASTM D2162, the primary method
for viscosity standards manufacture. they are dual UKAS certified to the
International Standards BS EN ISO / IEC 17025 and ISO 17034.
Our certified pH buffer range include solution for pH 4.00, 7.00
and 10.00 certified at either 20 °C or 25 °C, specifically used for
verification and calibration checks of pH meter instruments.
These range of liquid colour standards includes AOCS-Tintometer,
ASTM, Gardner, Lovibond RYBN, Pt-Co and Saybolt Colour, the key colour scales
applied to oils, fuels & chemicals.
ISO 17025 / ISO 17034 certified Density standards are for the
verification of instruments used to measure density of materials which are
fluid at the desired test temperature within the range of 15 °C to 150 °C
Paragon Scientific produces a range of refractive index
standards for use in the calibration and verification of all types of
refractometer e.g. handheld, Abbe and high accuracy digital instruments.
Certified Ethanol Standards – % ABV (Alcohol by Volume)
ISO 17034 & ISO 17025 Certified Ethanol Standards are
designed to be used for the calibration and/or verification of alcoholmeters or
densitometers.
Paragon ISO 17025 / ISO 17034 Relative Density standards are
designed for the calibration or verification of instruments used to measure
density and relative density of materials.
Secondary Working
Flash Point standards
Secondary Working Standards (SWS’s) are flash point standards
designed to be used on a frequent basis in order to verify test equipment
functionality on an on-going basis.
Smoke Point
Reference Fuel Blends
These products are ideal for the calibration and/or verification
of analytical instrumentation for automatic or manual measurement of smoke
point using ASTM D1322, IP 598 or other applicable methods.

control procedures used for analysing sulfur content in petroleum products.
Total Acid Number (TAN) Standards
Paragon’s ISO 17025 & ISO 17034 Acid Number (AN) standards
are specifically manufactured for the verification of analytical instruments
used to determine acid number by potentiometric titration.
Total Base Number (TBN) Standards
Paragon’s ISO 17025 & ISO 17034 Base Number (BN) Standards
are specifically manufactured for the verification of analytical instruments
used to determine base number by potentiometric titration.
These check oils are for the validating the performance of
Cold-Cranking Simulator and Kinematic Viscometers by measuring commercially
available formulated engine oils.
