Traceable® Dual-Display Digital Stopwatch

Quartz-crystal design is accurate to 0.0005%—over 100 times more accurate than other stopwatches. Resolution is 0.01 second. Times to 9 hours, 59 minutes, 59 seconds, and 99 hundredths. Precise, Traceable® timing for enzyme tests, viscosity measurements, animal studies, and all 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.

Tough, water-resistant ABS plastic case features tongue and groove craftsmanship and O-ring construction to seal out moisture, dust, and fumes encountered in harsh lab, plant, or field environments.
