Milwaukee M10442 1500 ppm TDS Solution Sachets (25)

The M10442 is a lab grade 1500 ppm TDS solution standard prepared against a NIST traceable potassium chloride solution.  It is used to recalibrate a conductivity meter or tester.  Refer to the meter or tester’s manual to find the correct calibration standard.      

TDS readings are affected by temperature.  To help with this, a chart of the actual µS/cm value at various temperatures is printed on each sachet. 

The solution is sealed in an airtight, tamper proof sachet.  It is labeled with the lot number and expiration date for traceability.
