A timer is designed to remind the lab worker of a set time that he has pre-set for some process like heating, stirring, hardening, cooling and the like.
Instead of waiting for the process to complete, the lab worker can take advantage of the short time that is usually a few minutes and do other chores.
The employee sets a time from one minute to 99 minutes, as soon as the timer beeps the time runs out.
The timer is small and light and can be hung on the garment or placed on the desk.
stopwatch
Used by the lab worker to check times of processes like up to change aggregation modes, color change etc.
