TDS Calibration Solutions Quality Solutions for Laboratory Applications • Safety data sheets · Safety data sheets for all Hanna solutions are available at hannainst.com or upon request. • Expiration date · The production batch number, expiration date, and temperature correlation table are reported on all Hanna calibration solutions. • NIST traceability · Standardized using a conductivity meter and probe calibrated against NIST primary standard solutions or primary standard solutions prepared following NIST guidelines. • Air-tight bottles · Air tight bottle with tamper-proof seal of freshness to ensure quality. • Single use sachets · Light block packaging prevents oxidation from UV light that could alter the value. Every sachet is as fresh as the day it was packaged. TDS Solutions Hanna TDS calibration solutions are prepared against a NIST traceable potassium chloride solution. Hanna TDS solutions have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution. Hanna’s line of TDS calibration solutions have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened bottle.
