Abstract
The utility model discloses a multifunctional laboratory timer comprising a timer host and at least one alarm extension which are independent from each other. When the timing of the timer host reaches the setting time, the timer host transmits the control signal to the alarm extension through wired or wireless communication mode to control the alarm extension for alarm prompting. In the utility model, by adopting the split-type structural design of one timer host matching with a plurality of alarm extensions, multiple timings can be set simultaneously on one timer host, and different alarm extensions can be controlled for alarm prompting when different timings are up. Different alarm extensions correspond to different laboratory equipment, so the problem of timing confusion owing to too many timers is avoided. Besides, non-contact induction buttons are adopted on the timer host for receiving the button operations of the experiment staff, so the sealability of the timer host can be improved, and the service life can be prolonged.
