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.
