H7039L is a premium quality 5,000 µS/cm conductivity solution standardized with a conductivity meter that has been calibrated with potassium chloride NIST 2202 SRM (Standard Reference Material) in deionized water for analytical use in accordance with ISO 3696/BS3978.
Additional equipment used in preparation of the solutions include certified weight-checked balances, Class A glassware and certified thermometers.
5,000 µS/cm conductivity standard that is prepared against a NIST traceable potassium chloride solution. Hanna conductivity 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 conductivity electrodes can be calibrated in just a few minutes, wherever you are working, thanks to our range of six conductivity solutions in different forms and values. Sachets, for instance, could be very useful out in the field as well as the laboratory.
- Air tight bottle with tamper-proof seal
- Ensures quality and freshness of solution
- Each bottle marked with lot number and expiration date
Hanna conductivity standards are specially formulated to have an expiration of 5 years from manufacture for an unopened bottle.
