Conductivity standard at 25°C is tested by an ISO 17025 Accredited (A2LA Ref: 6739.03) Test Method and NIST traceable. The product is aqueous based; non-hazardous and accurate to a specification of ±1%. The product because it is aqueous based; has a low temperature cŒfficient of variation and guaranteed stability throughout its entire shelf life; even after opening the bottle.

• NIST traceable
• Aqueous based, thereby eliminating any errors attributable to matrix mismatch
• Each bottle is supplied with a comprehensive Certificate of Analysis and has a table of conductivity variation with temperature printed on the product label
• Low temperature cŒfficient of variation, reduces measurement errors and enables non-temperature controlled use and is suitable for field work
• High accuracy ±1% at 25°C, enables the standards to be used as calibrators and/or controls, in accordance with the most exacting industrial requirements
• Guaranteed stability throughout entire shelf life, even after opening the bottle, eliminates the need to open a fresh bottle of standard every time it is used
