B130 pH Buffer Solution Kit, 1 Pt Each, B104+B107+B110 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

WD-00652-24 Traceable® Conductivity and TDS Standard, Batch-Tested, 10 μS; 500 mL by Oakton

• Oakton® Traceable® conductivity and TDS standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25°C-convenient!!
• Average accuracy at 25°C is ±0.25 microsiemens for 1, 5, 10 microsiemen (μS) solutions, or ±0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater
• Conductivity options range from 1 to 200,000 μS/cm
• Batch-tested solutions are lot certified; a few bottles from a single lot are analyzed

METHODS SUPPORTED

Certified reference material meets test requirements for Federal, State, and local agencies, CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, and ISO. Traceable® Conductivity Standards complies with and is essential for use in these official methods: AOAC 973.40, EPA 120.1, Standard Method 2510 (APHA, AWWA, WEF), ISO 7888, DIN 38404, ASTM D1125, USGS I-1780, USP 645, and for A2LA/NVLAP accreditations/ISO 9000 certifications. Material may be used to calibrate all conductivity meters and to determine all conductivity cell constants.

A2LA ACCREDITATION ISO/IEC 17025:2005 (1750.01)

To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory. A2LA accredited certification provides the highest achievable level of quality assurance, documentation, and accuracy. Conductivity Standards are produced in an A2LA accredited ISO/IEC 17025:2005 (1750.01) calibration laboratory. Additional certifications include ISO 31 (certificate content) and ISO 35 (statistical analysis), plus ISO 9001 (certified quality manufacturer).

• All Oakton® Traceable® conductivity standards are NIST-traceable reference materials
• Supplied with a calibration report from an ISO 17034 and ISO 17025 accredited laboratory
• These standard solutions let you calibrate conductivity instruments to ensure accuracy
• If unopened, shelf life is one year; once opened, shelf life will vary by solution value
• Use when readings are expected to be around 10 μS/cm

INCLUDES

temperature compensation chart, TDS conversion chart, and NIST-traceable calibration certificate with data.

Part Number: MCSCREWK1

94411-35 Traceable® Key-Chain Digital Timer with Calibration by Digi-Sense

Use as a key chain, or clip to a button hole of your lab coat to take it wherever you go. Program countdown mode from 20 hours to 1 minute; alarm sounds when timer reaches zero. LCD display shows time remaining in hours and minutes. In stopwatch mode, counts up to 20 minutes and repeats.

Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately.

NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.

• Get accurate, reliable measurements with included NIST-traceable calibration

Includes

One 1.5V button cell battery and NIST-traceable calibration certificate with data.
