Wear this extraordinarily lightweight (less than one ounce) timer around your neck. Program it to count down and alarm from 24 hours to 1 second. Resolution is 1 second and accuracy is 0.01%. Also has a stopwatch (count-up) and time-of-day display. Digits (1/2" high) are large and readable. Touch-of-a-key operation permits instant-replay timing for repetitive testing. Memory never changes until you reprogram it, saving valuable time.
To assure accuracy an individually serial-numbered Traceable® Certificate is provided. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Also supplied with battery and lanyard.
