Milwaukee M10038B – 6.44 ppt TDS Calibration Solution (3 x 20mL Sachets)
Keep your TDS meter or conductivity tester reading accurately with the Milwaukee M10038B — a lab-grade 6.44 ppt TDS calibration standard prepared against a NIST-traceable potassium chloride (KCl) solution in deionized water. Formulated to ISO 3696 / BS3978 standards, this solution ensures your instrument delivers reliable, repeatable results every time.
Each single-use 20mL sachet is sealed against light and air, eliminating contamination risk and making on-the-spot field calibration fast and clean. A printed temperature compensation chart on every sachet shows actual ppm values across a range of temperatures — critical for accurate TDS measurement in variable conditions.

Compatible Instruments
Check your meter or tester manual to confirm the correct calibration standard. This solution is designed for use with Milwaukee TDS meters and testers requiring a 6.44 ppt standard, including models compatible with M10038 and cross-compatible with Hanna HI70038.
Why Calibrate Regularly?
Conductivity and TDS probe performance degrades over time due to residue buildup and electrode aging. Regular calibration with a certified reference solution is essential for water quality testing, hydroponics, aquaculture, laboratory analysis, and food & beverage QC applications.
