Five certified conductivity standard solutions for verification and calibration of conductivity instrumentation have been developed. They cover a range of 25-100,000 [micro]S/cm with traceability to ASTM and NIST. The standards are produced in the company's ISO 9001 certified facility with processes similar to those used to calibrate high-accuracy conductivity sensors. The standards are packaged in sealed 500 mL bottles with certificates of analysis. Mettler-Toledo Thornton Inc ., Bedford, Mass., www.thorntoninc.com
