98766-08 Traceable Universal Digital Stopwatch with Calibration by Digi-Sense

When zero is reached, the alarm sounds and repeats the countdown from the programmed time. Timing cycle repeats automatically, or until stopped; count area of display shows number of repeat cycles. The dual-line LCD continuously displays time remaining to zero - ideal for analysis that must be noted at routine intervals.

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
• Provides repeat function of countdown alarm timing
• Set pacer function from 0.1 (600 beats/min) to 30 seconds (2 beats/min) - beat counting up to 99 times

Includes

One 3 V button cell, lanyard, and NIST-traceable calibration certificate with data.

WD-00651-38 Traceable® pH Standard Buffer with Calibration, Yellow, pH 7; 1000 mL by Oakton

Oakton pH buffers are compared against, and are traceable to, NIST Standard Reference Materials. Each bottle includes a NIST-traceable calibration report stating accuracy at 25°C to ±0.010 pH. Color-coded and colorless buffers are available in 500-mL, 1-L, or 4-L packaging sizes. Additional values and packaging sizes are available. Store at room temperature.

Certified Reference Materials (CRM) meet federal, state, and or local agencies' strictest mandates, and deliver exact calibration results for any pH meter. A2LA ISO/IEC 17025:2005 (1750.01) (Calibration Laboratory) and ISO Guide 34 (Certified Reference Material Producer) provide highest achievable levels of product production, documentation, and accuracy. Additional accreditations include ISO 31 (content) and ISO 35 (statistical analysis). ISO 9001 ensures that world-class product standards for Materials are always met.

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.

NIST-traceable reference materials include a calibration report from an ISO 17034 and ISO 17025 accredited laboratory

• Choose from clear or color-coded standards from common calibration points
• 1000 mL (32 fl.oz.) capacity
• Calibrate at pH 7
• Easily identify yellow color-coded formula
