This unique portable timer is easy to use. It counts down, alarms, functions as a stopwatch and also has a time-out feature in both up and down counting. Program it in the countdown mode in minute increments from 20 hours to 1 minute with fast and intuitive three-key operation and Quartz-crystal 0.01% accuracy. The big-digit, 1/3-inch-high LCD display is easy to read and always shows time remaining in hours and minutes. One of the handiest timers ever designed–holds your keys or hooks onto your lab coat.
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 rugged, chemical-resistant ABS case, and battery.
