94461-22 Traceable Dual-Display Two-Memory Digital Timer with Calibration by Digi-Sense

Perform repetitive testing by using the memory function to recall a set time on each channel. Each channel has a distinct audible alarm and flashes a "TIMES UP" message when the set time is reached. Slide switch on the side selects between the channels for time programming.

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.

Includes

Built-in stand, pocket clip, magnet, one 1.5 V button cell battery, and NIST-traceable calibration certificate with data.
