Catagory All TRM , Secondary Electrolytic Conductivity Solution (0.001 mol/l KCl)


ใบรับรองของสารละลายบัฟเฟอร์ TRM-S-2001 ถึง TRM-S-2008 และ สารละลายมาตรฐานสภาพการนำไฟฟ้า TRM-S-2017 ถึง TRM-S-2019 ขอชี้แจงดังต่อไปนี้

"According to JCGM 200: 2012 International vocabulary of metrology-Basic and general concepts and associated term (VIM) 3rd edition,measurement uncertainty is defined as non-negative parameter characterizing the dispersion of the quantity values being attributed to a measurand, based on the information used.Therefore, the uncertainty of pH standard solution and electrolytic conductivity standard solution as shown in the certificate does not show the sign (+) for the expanded uncertainty"
