This simple-to-use timer only has three buttons for easy operation. Large, 3/4" high digits can be seen up to 20 feet away. Count down from up to 20 hours in one-minute increments. When the timer reaches zero, an alarm will

Traceable® Products come with an individually numbered Traceable® Certificate provided with each unit, assuring accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. The certificate indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. Every Traceable® product undergoes an intense vetting process before it can carry the Traceable name, saving you both time and money by eliminating the need for separate calibration.

Guaranteed to have at least one year of calibration remaining on certificate.
