Sper Scientific Talking Lab Countdown Timer – Voice Announcements, Large Display & Clock Mode

Effortless, voice-guided lab timing

The Sper Scientific Talking Lab Countdown Timer brings hands-free timing to your bench, delivering a clear human voice that announces time as you work. No more constant glances at the display; the timer speaks so you can stay focused on your experiment.

How the audible countdown helps your workflow

• Hourly updates during a countdown keep you oriented without interrupting your task.
• In the final hour, updates occur every 10 minutes, every minute during the last 10 minutes, and every second in the final 10 seconds.
• Audible cues give you time to wrap up steps and be ready for the final alarm.

Key features at a glance

• Counts up or down to 24 hours and runs alongside the clock.
• Voice confirms timer and clock settings as you press buttons; you can turn the voice on or off.
• Recalls previous countdown settings for immediate reuse; stores another frequently used setting for quick access.
• Six distinct final alarm sounds help you identify which timer has alarmed when multiple timers are in use.
• Large 3/4 inch display with intuitive icons supports quick checks in bright or dim environments.
• Built-in stand for bench-top use, a magnetic back for metal surfaces, and a pocket clip for on-the-go use.
• Includes button cell batteries; optional NIST traceable certificate of compliance is available.

Practical, real-world uses

Whether timing a reaction step, an incubation, a gel run, or a multi-stage procedure, this timer helps you maintain rhythm without constant reference to a clock. In low-light labs, the voice prompts can be especially helpful, and the clock mode keeps you informed even when the light is scarce.
