Traceable nano timer. Small timer - large display: At the press of a button, timer displays countdown alarm time/stopwatch (count-up) time, and time-of-day (AM/PM and 24-hour format). Accuracy is 0.01 percent. High-decibel alarm sounds for 1 minute. Count down or up to 23 hours, 59 minutes, 59 seconds on the two timing channels. For repetitive tests, the unit s two channel memory automatically returns the display to the original programmed time. Three-eighths-inch-high digits may be read from 10 feet. Traceable to NIST for accuracy: 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). Supplied with 2-year silver oxide battery, clip, stand, and magnet on back.
