98766-78 Traceable® Digital Count Down Timer with Calibration; 99min/59s by Digi-Sense

Three-key operation makes this compact timer incredibly easy to learn and use. Timer counts down from 99 minutes, 59 seconds in 1 second increments. Alarm sounds for 30 seconds and then silences automatically. Unique memory resets display to last programmed time for quick repeat of frequent, routine tests.

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
• Large, three-button operation for ease of use
• Count down timer from 99 min, 59 sec

Magnet, flip-open stand, clip, one AAA battery, and NIST-traceable calibration certificate with data.

94461-15 Traceable® Flashing LED Big-Digit Timer with Calibration; Single-Channel by Digi-Sense

Large digits permit viewing from across the lab. When counting down, green LED flashes every second for the last ten seconds; red LED flashes when zero is reached and the alarm is sounding. Adjustable alarm volume has three settings: high, low, and off. Timer also counts up showing elapsed time after zero was reached. Features magnetic back, flip-open easel stand, and an opening for a lanyard.

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 a 17025-accredited calibration test lab has confirmed 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.
