WD-00652-34 Traceable® Conductivity and TDS Standard, Batch-Tested, 100,000 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 100,000 μS/cm

INCLUDES

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

98766-76 Traceable Talking Digital Timer with Calibration by Digi-Sense

Talks, counts down, counts up and tells time with precision! A clear human voice announces time remaining in count-down mode - no need to visually check. Announcements increase in frequency as time approaches zero. Use for continuous timing or with unlimited time-outs. In clock mode, press any button and the voice will announce the time. Perfect for low-light applications, darkrooms, and activities that require your full attention.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Timer speaks in English announcing time remaining, time elapsed since alarm was triggered, and time of day
• Purchase multiple units and set each one to a different alarm sound - six distinct alarm sounds

Includes

Built-in tilt stand, pocket/belt clip, magnetic strip, two 1.5 V button cell batteries, and NIST-traceable calibration certificate with data.

94411-01 Traceable® Continuous Visual Alarm Timer with Calibration by Digi-Sense

With a flip of a switch this innovative timer has a selectable bright flashing LED visual alarm or audible alarm. Ideal for noisy environments. Timer counts down from 9999 minutes in minute increments. Automatic memory resets the display to the last programmed time for repetitive tests.

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

Two AAA batteries and NIST-traceable calibration certificate with data.
