About Timing Functions

Style Q timers have an extra-loud alarm that can be heard over background noise in a typical manufacturing environment.

Timers with a calibration certificate traceable to NIST have been tested to NIST standards to ensure accuracy.

Timers with a memory function automatically return the display to the last programmed time. Good for timing repetitive intervals.

Multifunction Smartwatch

Keep your phone in your pocket and your hands free—these smartwatches perform a variety of functions on your wrist. They connect to Apple and Android phones via Bluetooth, informing you when calls, texts, and other notifications arrive. Designed for harsh environments and rugged use, they meet military standards for resistance to hot and cold temperatures, shock, splashes, and submersion in up to 100 meters of water. These watches have a compass and GPS for tasks such as navigation, tracking and saving location coordinates, and calculating the area of a location by walking the perimeter. With weather and elevation monitoring, you can set the rate of barometric pressure change that will trigger a storm alert. These watches track health and fitness metrics over time, including heartrate, blood oxygen levels, and exercise. They have a solar battery in addition to a rechargeable lithium-ion one to extend the time between plug-in charging.

Metal- and X-Ray-Detectable Stopwatches

Breakaway Clasp

Track time on food processing lines while reducing the risk of contaminating the food. To help you comply with Hazard Analysis and Critical Control Point (HACCP) programs, these plastic stopwatches contain metal and chemical additives that will set off metal detectors and show up on X-ray machines. They’re also bright blue, so it’s easy to spot any broken pieces that may fall into your line. They are FDA compliant for direct contact with food.

These stopwatches have a lanyard with a breakaway clasp, which keeps you safe while working near your line—the clasp will break if the lanyard gets caught.
