B104 pH Buffer Solution, pH 4.01 Buffer (Red), 1 pint (473ml) by Sensorex

Sensorex supplies pH buffers as pre-mixed, ready-to-use, color-coded liquids.-- red (pH4.01), yellow (pH7.00) and blue (pH 10.00). All buffers are guaranteed accurate to within +/- 0.01 pH units @ 25 deg C. Available sizes include pints(473mL), quarts(946mL) and gallons(3.786L). Buffer labels include pH vs. temperature information for precise calibration. Custom buffers are also available on an OEM basis. Please contact Sensorex regarding your requirements.

Electrode storage solution is available in pint and gallon sizes. This is the same solution that is shipped with all pH electrodes and ensures electrodes are ready for immediate use. Storage solution is recommended for long-term electrode storage since it is not color-coded and will not impart any color to the electrode's reference junction.

Features:

• Choice of pH 4.01, pH 7.00 and pH 10.00 or custom formulations
• Pint, Quart and Gallon Sizes
• NIST Traceability Certificates Available at Additional Cost
• Private/OEM Labeling Capability
• Color-Coded for easy recognition

MA9065 111,800 μS/cm Conductivity Calibration Solution - 230 ml Bottle by Milwaukee

The performance of conductivity probes are affected by use due to residue build up and aging.

MA9065 is a lab grade 111,800 μS/cm 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 bottle

Milwaukee conductivity solutions are labeled with the lot number and expiration date and packaged in an air tight, tamper-proof sealed bottle.

DESIGN FEATURES

• Fundamental 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.
• 5 year expiry date.

TDSK1413/P Conductivity Solution, 1413uS KCl, 1Pt. by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.
