主要特点

Compact size and two channels make this timer ideal for the lab. Set two channels independently in count-up or countdown mode. Distinctive alarm sound for each channel beeps for one minute after set time has elapsed. For repetitive tests, memory function automatically returns the display to the original set time.
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.
