Model: 4270 | Order No: 4270/A
Use this conductivity standard to accurately calibrate conductivity, resistance and TDS instruments. Use this solution when readings are expected to be around 5 μS/cm, 0.2 MΩ or 3.3 TDS/PPM.
Use the Traceable 4270 Conductivity and TDS Standard when you want accurately calibrated equipment in your lab. All Traceable conductivity standards are NIST-traceable reference materials, giving you confidence in the precision and accuracy of your newly-calibrated equipment. Use this solution when your desired equipment readings are 5 μS/cm, 0.2 MΩ or 3.3 TDS/PPM. Made in the USA.
