About This Product

Large-Digit Stopwatch and Countdown Timers for Plants, Hospitals and Labs

Electromed's Stopwatch and Countdown Timer are large 7-segment LED timers built on the same jumbo clock platform, readable from 20 m to 125 m depending on digit height. Use them wherever people need to see elapsed or remaining time at a glance.

The Stopwatch counts up from zero and is started, stopped and reset by a push button or a potential-free contact from a PLC. The Countdown Timer counts down to zero; the time is set over WiFi from a phone, and a relay output switches a buzzer or hooter at zero. Choose a 4-digit MM:SS display or a 6-digit HH:MM:SS display.
