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 a distinct electronic alarm and visual indicator when zero is reached. The alarm may be turned off or it is silenced automatically after 1 minute.

Automatic or Programmable memory

For repetitive timing, the microcomputer chip permits setting 2 countdown times into memory. During normal timing the memory recalls the last countdown time set. Large 5/8-inch high LCD digits may be read from 20 feet.

Unique visual indication for each channel 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 alarm volume has three settings which allow setting the timer to a high decibel for noisy areas, low for quiet environments or off (muted) for silent only visual flashing LED operation.

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). Magnetic back allows timer to be placed on any metal surface such as incubators or water baths.
