Calibration Standards & Low Level Verification Standards

Aqueous Conductivity is a key parameter used in the production of Ultrapure Water (UPW) & Water for Injection (WFI) in the Pharmaceutical & Life Science Industries. Altus Science are an ISO 17025 & ISO 17034 accredited manufacturer of NIST Traceable Conductivity Reference Materials. With a global network of channel partners, we supply all of the Calibration, Validation & Verification Standards required to maintain compliance to USP Chapter 645, EP Chapter 2.2.38 & all other major pharmacopeia’s

Our independence, together with a rigorous Quality Management System (QMS), allows us to manufacture unbiased Aqueous Conductivity CRMs to the highest quality standards, giving you an accurate record of instrument performance, regardless of which Conductivity Meter you use. Each individual standard is fully traceable to NIST & comes with its own certificate of analysis, accredited to ISO17034 & ISO17025

Altus Science manufacture Low Level Verification Standards, starting at 1.3µs/cm. This helps give you complete confidence that your Conductivity sensor is performing as it should do, close to the true Conductivity value of your PW, UPW or WFI. Our Standards are produced in an aqueous matrix, matched to the matrix of samples typically measured in the Pharmaceutical & Life Science industries, helping to avoid matrix errors. Whether you are validating a method, calculating linearity or performing daily Calibration Checks, Altus Science have the standards and technical expertise to help you.
