Reliable reference materials are necessary to standardize reagents, and to check the titrator according to the requirements of ISO,ASTM,JIS guidelines.

AQUAMICRON offers a series of excellent standards that have advantages:low toxicity,easy to use and to manage.To ensure the high quality,all of our Water Standards are manufactured under stricted control and accurately measured using validated procedures traceable to the international prototype at the BIPM in France.

Also AQUAMICRON Liquid Water Standard(AWS01,02,10,100)is directry traceable to NIST SRM2890.
