The Rx-4 uses a rotating turntable and an automatic gate to feed pills through an optical infrared sensing array.  This allows for fast, accurate, hands-free counting.
Listed accuracy is 99.97%, but when used as described in the included Operator’s Manual, the Rx-4 is designed to simply not miscount.
The Rx-4 will count round, aspirin-size tablets at a rate of approximately 500 per minute, and will count large capsules at approximately 350 per minute.  Even at its slowest speed, The Rx-4 is still faster and more accurate than hand-counting.

That depends. Semi-rounded, symmetrically-shaped items like oblong beads and hex nuts can work quite well.  Asymmetrical items with sharp corners and/or odd shapes such as screws or flat-backed crystals do not.  Also, spherical, ball-shaped items do not behave properly on the turntable.  Feel free to contact us if you want to send in some samples to test.
