Calibrate your equipment for maximum accuracy
- Reagent-grade secondary standards
- Traceable to NIST standards
- 1,000, 10,000, 50,000 and 100,000 µmhos/cm
Each bottle includes detailed instructions and a table of corrections at temperatures between 20 and 30°C. Packaged in glass quarts. The 1,000 µ solution has a tolerance of 0.50%. The 10,000 and the 100,000 µ solutions have a tolerance of 0.25%. Solutions for routine calibrations are packaged in plastic pints and have nominal values ±1.0% (Thomas numbers 3241M30 to M45).
