Traceable Digital Count Down Timer with Calibration, 99min/59s

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.
