主要特点

Count up/down timer can be programmed to count up or down to 100 hours with a 1-second interval. After the count down cycle, the timer counts up to indicate elapsed time and sounds an audible alarm when time has elapsed. Memory recalls the last setting for easy reuse. Timer can double as an alarm clock.
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.
