Dear Supplier, We are looking for an interval timer. It will beep on every interval we set. Eg, if we key in 17 seconds, and it will beep twice at 17 second, then stop, then beeps again at 34 second and etc. Please send more information and quotation for 50 pieces of samples to my email bree@showcasemedia.com.au. Thanks, Bree Contact Name: Ms bree LI Company: Show case digital media Address: 29 westwood drive Country/Region: Australia Business Email: bree@showcasemedia.com.au Telephone: 61-03-92176025 不好意思，大家自己翻译下，顺便支持我哦~
