Control Company’s Traceable® Flashing LED Big-Digit Dual Channel Timer allows simultaneous timing on two distinct channels from 99 hours, 59 minutes, 59 seconds to 1 second. Resolution is 1 second; accuracy is 0.01%. Each channel has a distinct electronic alarm and visual indicator when zero is reached. The alarm may be turned off or it silences automatically after 1 minute. Large 5/8-inch high LCD digits are easy to read. When counting down, green light flashes every second once the countdown time reaches 10 seconds. 

Red light flashes when zero has been reached and the alarm is sounding. Adjustable volume has three settings—high decibel for noisy areas, low for quiet environments, and off (muted). 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). Supplied: batteries, magnetic back, flip-open stand, spring-loaded clip, lanyard, Traceable® Certificate. Size: 3½ x ⅝ inches. Weight: 3 ounces.
