When accuracy is critical, you can't afford to leave your conductivity measurements to chance. Our Thermo Scientific™ Orion™ conductivity standards are NIST™ traceable and available in pouch or bottled packaging. Whether you are in your lab or in the field, our standards ensure that you get the measurements you need, with results you can trust.
Suitable for ultrapure water measurements, our low-level conductivity standards will help you meet your accuracy requirements. Our low-level conductivity standards hold their value, while others can be affected by container and atmospheric contamination. For USP <645> cell constant verification and other critical pure water applications, our standards are the ideal choice.
