Milwaukee M10038B 6.44 ppt TDS Calibration Solution Sachets (25)

The M10038B is a lab grade 6.44 ppt TDS solution standard prepared against a NIST traceable potassium chloride solution.  It is used to recalibrate a conductivity meter or tester.  The correct calibration standard for a meter can be found on the meter or in the manual. 

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

Solutions are packaged in an air-tight, tamper-proof sachet.  They are labeled with the lot number and expiration date for traceability.

Features:

• Important for accurate TDS measurement, the performance of conductivity probes is affected by use due to residue build up and aging
• Factory calibrated with potassium chloride NIST 2202 SRM (Standard Reference Material) in deionized water for analytical use in accordance with ISO 3696/BS3978
• Sealed against light and air
• Ideal for on-the-spot calibration
• Simply open, insert the tester or electrode into the sachet, and calibrate
• Each 20 mL sachet is marked with lot number and expiration date
• A temperature chart of the actual ppm value at various temperatures is printed on each sachet
• 5-year expiry date
