Up/Down Timing and Clock

Traceable Flashing LED Big-Digit Dual Channel Timer allows simultaneous programming of two different activities from 99 hours, 59 minutes, 59 seconds to 1 second. Resolution is 1 second; accuracy is 0.01%. Each channel has distinct electronic alarm and visual indicator when zero is reached. Alarm silences automatically after 1 minute or may be turned off manually. Unique green light flashes every second once countdown time reaches 10 seconds. Red light flashes when zero has been reached and alarm is sounding. 

Adjustable alarm volume has three settings which allow for noisy areas, quiet environments, or for silent, visual-only operation (alarm off). For repetitive timing, microcomputer chip permits setting two countdown times into memory. During normal timing, memory recalls last countdown time set. Unit has easy-read ⅝-inch high LCD digits. 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).
