Transparent amber case with high-strength magnet (Neodymium Iron Boron, Nd-Fe-B) hidden in the back clip. Physical sizes measured as 69 x 49 x 15 mm. The maximum timing can be set to 9999 minutes, and the minimum set countdown interval is 1 minute. Count down to zero and then count up.
When the countdown reaches zero, there are three continuous warning methods: 1) LED light flashes, 2) buzzes, 3) full LCD screen flashes. With the full LCD screen flashing, the buzzer sounds once every second, and the LED light flashes once at the same time. After 12 seconds it becomes 2 times per second, after 24 seconds it becomes 4 times per second, after 36 seconds it becomes 8 times per second, after 48 seconds it keeps flashing and beeping without interruption. Unless you hit the "stop" button. This type of warning provides the most effective warning for users of countdown devices, especially in dimly lit areas.
The countdown interval can be set by the user, and the adjustment unit can be seconds, minutes, hours or days. It can also be a pre-programmed interval, a timer with a fixed countdown time that can be used to remind regular maintenance of expensive equipment, replace filters with a limited lifespan, or regular events.
