Our laboratory timers, stopwatches, clocks, and controllers are ideal for anywhere in the laboratory, out in the field or for areas where you need to keep your eye on the time. Don't rely on your smartphone and worry about exhausting your battery power. Count down the hours, minutes or seconds with our wide range of analog and digital general- and special-purpose clocks and timers for keeping accurate time up to 1/10,000 of a second. We offer analog and digital clocks with large digits, clip-on timers for when you are on-the-go, radio controlled or atomic clocks, and water- and dust-resistant clocks with sealed cases for those challenging areas. LCD models are ideal for viewing from long distances. Radio-controlled or atomic clocks are automatically adjusted by a controlling radio signal from NIST in Boulder, Colorado. Get accurate, reliable measurements and meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements with included NIST-traceable calibration on many models of timers and clocks.
