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

主要特点

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.
