Traceable® Clip-It™ Memory Digital Alarm Countdown/up 1 Channel Timer, which counts up to 100 Hours with a NIST Traceable® Calibration Certificate (each)

Clip-It™ Timer counts down, alarms, and functions as a stopwatch
The handiest timer ever designed clips to your lab coat, belt, notebook, clipboard, or anywhere. You’ll never lose your own personal timer.

Six-digit LCD always shows the time remaining in hours, minutes, and seconds
Program it in the countdown mode, in 1 second increments, from 100 hours to 1 second. At zero, a loud-beeping alarm sounds for 60 seconds or may be silenced manually. In the stopwatch mode, it times from 1 second to 99 hours and then repeats. Accuracy is 0.005% quartz crystal. Also has a time-out feature in both up and down counting.

Clip-It™ Timer is the perfect reminder when you have to be away from the lab
Notifies you when to read a color change, remove a sample from an oven, or go to a meeting. Big-digit, 1/3-inch-high display is easy to read. Five-button operation is quick and intuitive (no need to ever read the directions). Stopwatch operation takes just the press of a single button. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
