Milwaukee M10442 1500 ppm TDS Solution Sachets (25) USEPA 330.5 reagent Single-junction probes are vulnerable toDescription The performance of conductivity probes are affected by use due to residue build up and aging. M10442 is a lab grade 1500 ppm TDS solution standard prepared against a NIST traceable potassium chloride solution that allows you to recalibrate your 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 the actual ppm
