MA9001 pH 1.68 @ °C/77 °F Calibration Buffer Solution: accuracy +/- 0.01 pH - 230 ml by Milwaukee

Probe calibration is a simple procedure for optimal performance and should be done any time your readings become suspect. Calibration should be performed at least once a month.

MA9001 is a lab grade pH 1.68 buffer solution certified to meet the standard to an accuracy of ±0.01 pH removing the inaccuracies involved with mixing buffers.

Milwaukee solutions are designed to help you achieve reliable and repeatable pH measurements while extending the life of your electrode.

DESIGN FEATURES

• pH 1.68 Calibration Buffer Solution (230 mL)
• Fundamental for the correct use of electrodes and for obtaining the most accurate and reproducible readings
• Sealed against light with air tight, tamper proof cap
• Ideal for fast calibration
• Simply open, pour into a beaker or container and insert the tester or electrode to start the calibration process.

59-180-1M RG59/U, BNC Male to BNC Male, 15 feet by Test Products International

50 Ohm, 75 Ohm, 93 Ohm. TPI BNC to BNC coax cable assemblies include: RG58/U (molded and assembled), RG59/U and RG62/U.

Features

• UL Listed Cable: Ensures quality and consistency in the cable construction.
• Boot is molded to cable connector for added strength: Limits the amount of bending the cable is exposed to at the connector to prevent cable breakage.
• Gold center pins: Ensures that there is a high quality connection maintaining the best return loss in high definition applications.
• Machined Brass Connectors: Unlike die-cast connectors, machined brass connectors have more precise tolerances, strength and positive mating meaning low signal loss for precise video and data applications.
• Boot is molded to cable connector for added strength
• 95% shielding
• 80°F temperature rating
• Multiple lengths up to 100 feet
• Individually bagged

• Custom designs or changes to this product are available upon request

TDS30000/P Conductivity Solution, 30,000ppm/30,100uS,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.

MA9063 84 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.

MA9063 is a lab grade 84 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.
