talking timer, traceable, big-digit

Traceable® Flashing LED & Big-Digit Dual Channel Timer

Unique visual flashing LED visual indicator. Allows simultaneous programming of two different timers from 1 second up to 99 hours, 59 minutes and 59 seconds. Resolution is 1 second; accuracy is 0.01%. Each channel has a distinct alarm and visual indicator when zero is reached. The alarm may be turned off or silenced automatically after 1 minute. The unique visual indication for each channel, when counting down, shows a green LED light flashing every second once the countdown time reaches 10 seconds. When zero has been reached, a red LED light flashes and the alarm is sounding. The alarm has three switch positions; high decibel for noisy areas, low decibel for quiet areas or off (muted) for silent visual flashing LED light operation only. Large 5/8” high LCD digits may be read from 20 feet.

NIST Traceable certificate with individual serial number is supplied with the timer. The timer comes complete with two AAA alkaline batteries, magnetic back, stand spring clip and an opening for a lanyard. Size is 3-1/2" x 3" x 5/8” (89 x 76 x 16mm); weight is 3 ounces (85 grams).

traceable instant recall memory timer

Traceable® Instant-Recall Memory Timer

Input a time and the instant memory always returns the display to the programmed time. This is the ideal timer to dedicate to a routinely timed test. Bright, extra-large, 5/8" (15.9mm) high digits count down at any set time from 99 minutes 59 seconds to zero. At zero a loud 30-second alarm sounds.

Designed specifically for routine tests, quality control requirements, and repetitive analysis; it is the lab workhorse. The unique memory feature encourages devoting this timer to one piece of laboratory equipment such as a water bath, oven, stirrer, or incubator.

Accuracy is 0.01%. Replaceable AAA battery powers the timer for three years of nominal use. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

Magnetic back allows placing timer on metal surfaces. It lays flat on a bench or may be placed vertically with the flip-open easel. A spring fastener clips to pockets. Battery included.
