Thomas 5046 Clip It Timer, 0.01 Percent Accuracy, 1-1/2" Width x 2" Height x 3/4" Depth

Traceable clip-it timer. 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 percent 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). Clip-it timer has a rugged, chemical-resistant ABS plastic case, magnet for placing on metal, and a 1-1/2-year, continuous-use, replaceable silver-oxide battery.
