Milwaukee M10038B 6.44 ppt TDS Calibration Solution Sachets (25) HM Digital TDS-4TMA Aquarium TDS Meter with Digital Thermometer and radon-222 contaminants that standardDescription The performance of conductivity probes are affected by use due to residue build up and aging. M10038B is a lab grade 6. 44 ppt TDS solution standard prepared against a NIST traceable potassium chloride solution that allows you to recalibrate your conductivity meter or tester. Check your meter or tester's manual to find the correct calibration standard for your meter. TDS readings are effected by temperature. To help with this, a chart of
