Precise, Traceable® timing for enzyme tests, viscosity measurements, animal studies, and other timed lab tests. Made for scientists in industrial, educational, hospital, and governmental labs who insist on the finest instrumentation. Engineered for ease of operation, accuracy, and reliability.

Traceable to NIST for accuracy
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). Quartz-crystal design is accurate to 0.0005%—over 100 times more accurate than other stopwatches.

Ten-hour timing
Functions include single-action, time-out, interval-split, cumulative split, continuous roll-over timing, and countdown alarm timing. Resolution is 0.01 second. Times to 9 hours, 59 minutes, 59 seconds, and 99 hundredths. Vivid, 3/8-inch high LCD digits are ideal for viewing in lab and field. Includes 1
