Check the listing for details. Milwaukee MA9062 1382 ppm TDS Conductivity Solution Bottle. Condition: New. Listed at 22.99 USD. DESCRIPTIONThe performance of conductivity probes are affected by use due to residue build up and aging. MA9062 is a lab grade 1382 ppm TDS conductivity 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.Conductivity readings are effected by temperature. To help with this, a chart of the actual µS/cm value at various temperatures is printed on each bottleMilwaukee conductivity solutions are labeled with the lot number and expiration date and packaged in an air tight, tamper-proof sealed bottle.DESIGN FEATURESFundamental for accurate conductivity measurement.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 with air tight, tamper proof cap.Each 230 mL bottle is marked with lot number and expiration date.A temperature chart of the actual µS/cm value at various temperatures is printed on each bottle.SPECIFICATIONSDescription: 1382 ppm TDS conductivity calibration solution Package: Bottle - size 230 mL Quantity: 1
