Adar Klepsydra 3-minute sand timer set includes ten compact, mechanical hourglasses in mixed colors designed to measure a fixed 3-minute interval. Each sand timer provides an immediate visual indication of elapsed time through visible sand flow between two glass bulbs sealed in a plastic frame. The simple, non-digital design requires no batteries and offers a tactile, easy-to-understand timing solution for short tasks and activities.
Advantages
The set of 10 Adar Klepsydra sand timers combines uniform timing accuracy for repeated short intervals with a portable, break-resistant frame and clearly visible sand motion. Mixed colors help with quick identification and task assignment, while the compact size allows easy placement on desks, in bathrooms, or in game settings. The mechanical mechanism ensures consistent three-minute measurements without setup or calibration.

How to use
Place the sand timer upright on a level surface and invert it to start the three-minute countdown; visible sand will flow from the upper bulb to the lower bulb and the interval ends when the sand has fully transferred. After use, return the timer to its original position for storage. No setup, power source, or programming is required, making each unit ready for immediate use in repeated sessions.
Usage recommendations
For reliable timing, use the sand timer on a flat, stable surface and avoid excessive shaking or dropping. Assign different colors to specific tasks or participants to streamline group activities. Replace units that show uneven sand flow or visible damage to the glass to maintain consistent three-minute measurements.
