The digital hourglass offers the simplicity of an hourglass by starting the count down as soon as it is turned over. Unlike a sand hourglass, the duration of the count down is adjustable between 1 second and 100 minutes. As the timer counts down, "digital sand" flows from the upper to the lower part. This gives a reading at a glance of time remaining. Time elapsed and remaining is also shown. Repeated identical timing operations only require inverting the hourglass, but different times can be easily toggled in. Use as a conventional timer is possible. One button cell battery is included.

With NIST traceable certificate of compliance: ESD810044C
Although small and easily portable, this timer features a large display with 18mm high digits. Also unique is an auto-power-off feature to extend battery life (operates only when the timer is idle for 10 minutes and will not interrupt a timing sequence). Counts down from 100 minutes with 1-second resolution. Short warning alarms sound at 3 and 5 minutes prior to the final 30-second alarm. Automatically records elapsed time following the alarm for up for to 20 minutes, or until stopped. A memory recalls the last timer setting for repetitive tests. Has a built in stand, pocket clip and magnetic back. One AAA battery included.
Dimensions: 65 x 65 x 15mm.

A unique and very useful timer, featuring a clear human voice. Eliminate the need to continually visually check time remaining via voice announcements that can be heard from anywhere in the lab. This allows you to concentrate on the experiment you are timing rather than on the timer. In the countdown mode, Talking Timer will announce the remaining time every hour. In the final hour it will announce the time remaining every 10 minutes, every minute in the final 10 minutes, and every second in the final 10 seconds. The audible countdown gives you time to return to your experiment and be prepared for the final alarm. A choice of six distinctive final alarm sounds makes it easy to identify which Talking Timer has alarmed should you wish to use more than one.
Talking Timer is also very useful for work in low light or in the dark where it would be difficult to see a normal timer display. In the clock mode, touch any button in the dark and Talking Timer will announce the time. A voice confirms the timer and clock settings as you key them in. You also have the option of turning the voice off.
Other features include a large 2cm display with icons to indicate various modes, such as voice on/off, count up/down, etc. Recalls the previous countdowns setting for immediate reuse and memorises another frequently used setting for reuse at any time. Counts up or down to 24 hours. Both functions and the clock work simultaneously.
Talking Timer is cleverly designed so that despite its sophisticated features it is very simple to use. It has a built-in stand for bench top use, clips to a pocket, or sticks to any metal surface with its magnetic back. Button cell batteries are included.
