HANNA HI70038P TDS calibrated liquid 6.44 g/L (ppt) /20mL * 25 packs

HI70038P is a good quality 6.44 g/L (ppt) TDS calibration solution standardized using a conductivity meter that has been calibrated in deionized water with potassium chloride NIST 2202 SRM (standard reference material) for analytical use in accordance with ISO 3696/BS3978. Other equipment used to prepare solutions includes certified weight check balances, Class A glassware, and certified thermometers.

• Convenience of individual packaging

• Ideal for users who don't calibrate often

• Due to its portability, it is ideal for field use

• Each bag is as fresh as the day it was packed

• The light block packaging prevents UV oxidation, which can alter the value
