We supply dual-accredited ISO 17025 and ISO 17034 Density Reference Standards Paragon. Paragon certifies these solutions for temperature ranges between 15 °C and 150 °C. The material must remain fluid at your desired test temperature. The manufacturer strictly certifies every batch using the ASTM D1480 methodology. Technicians typically use these fluids in modern density measuring equipment. They work perfectly with oscillating U-tube methods like ASTM D4052. You can also apply them to IP 365 and equivalent international methodologies. This comprehensive product line also features a pure water density standard. Paragon accurately certifies this water standard at 15 °C, 20 °C, and 25 °C. They apply the same strict ASTM D1480 methodology for this specific certification.
