Calibration & Verification Standards

Flash Point Standards

Certified Reference Materials
Ensures good inter-laboratory correlation. Full Traceability to National Standards. Manufactured using independent testing laboratories across Europe. Round Robin method (except for UKAS certified density standards PDEN1, PDEN2, PDEN3)

Colour Standards
These CRMs are ideal for routine calibration of colour measuring instruments, verification of test data and ensuring good inter-laboratory or inter-instrument correlation. The range of liquid standards includes AOCS-Tintometer, ASTM, Gardner, Lovibond RYBN, Pt-Co and Saybolt Colour, the key colour scales applied to oils, fuels & chemicals. They are supplied with full traceability to internationally recognised standards, either UKAS to ISO 17025 (ASTM, Gardner & Saybolt Colour) or the ISO 9001 quality system (AOCS-Tintometer, Lovibond RYBN & Pt-Co Colour). Each standard comes in a 500 ml bottle with a 12-month guarantee of colour stability and full certification including MSDS.

Conductivity Standards
Conductivity has a wide range of applications and is used in various industries including, semiconductor manufacturing, power generation, chemical, pharmaceutical, food and beverage processing, metal and mining, textiles, pulp and paper and environmental monitoring of water quality. In most cases conductivity is an aqueous based test where it proportionally reflects the degree of water purity, the lower the conductivity of water the higher it’s purity.

Custom Blending
