Control Co.’s Traceable Extra-Extra-Large-Digit Countdown Timer has reliable three-key operation to make easy work of programming countdown settings in 1-sec increments. The timer counts down from 99 min, 59 sec and the extra-large 1½ -inch-high digits can be seen from anywhere. The single channel counts down to zero, the alarm sounds and then the timer begins to count up showing time elapsed since alarm. The memory returns display to previously programmed countdown time. Resolution is 1 sec and accuracy is 0.01%. To assure accuracy, an individually serial-numbered Traceable Certificate is provided from the company’s ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST.
