Traceable® Digital Alarm Countdown/up 1 Channel Timer, which counts up to 100 Minutes with a NIST Traceable® Calibration Certificate (each)

Numbered keys make it a breeze to set a countdown time
Remarkable timer counts down with an alarm and counts up with a time-out feature. Program it to count down from 99 minutes, 99 seconds to zero in any second increment. In the stopwatch mode, the unit counts up to 59 minutes, 59 seconds, and automatically roll over to zero and continues timing. Large, 3/8-inch-high display and vivid LCD digits continuously show time and are readable from 8 feet. Loud, high-decibel alarm may be turned off manually or is automatically silenced after 1 minute. Individually numbered keys make setting time faster than units with up/down buttons. Timer is accurate to 0.01%.

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).
