This row counter uses magnetic induction for accurate counting and is easy to install. The electronic counter features a Counting/Pause button to stop counting; after 0–30 seconds, the LCD display automatically turns off and enters standby mode. Press the button again to reactivate the display and resume counting. The counter has a shockproof design that ensures stable and reliable operation, free from mechanical wear. Made of durable plastic, this digital counter is sturdy, safe, and built for long-term use. It operates on a standard AA battery (not included), eliminating the need for external power.
