How It Works

It’s simple. Place any quantity of tablets or capsules on the Rx-4’s turntable disc surface, enter-in the counting mode and desired quantity on the keypad, press “Start” and let the Rx-4 Automatic Tablet & Capsule Counter do the rest.

The Rx-4 is fast — counting tablets and capsules at a rate of up to 500 pills per minute — and accurate, virtually eliminating miscounts.

The Rx-4 features three counting modes to perform any counting task:


Simply enter the quantity and the designated number of tablets or capsules is dispensed into the top collection drawer.

When the drawer is removed, excess tablets or capsules on the disc surface are automatically deposited into the bottom drawer for return to inventory.


Ideal for pre-packing and filling multiple medication vials with the same tablets or capsules.

Enter the desired per-vial quantity and excess tablets or capsules will remain on the turntable for continuous dispensing.

Use the included vial drawer attachment for Direct Vial Filling.


Simply press the “Start” button and the Rx-4 will count all inventory on the turntable.

The Rx-4 is the most economically-priced counter available, and is backed by a One-Year Manufacturer’s Warranty.

Every Rx-4 comes with a 30-Day Money-Back Guarantee.  If the Rx-4 does not satisfy your needs within the first 30 days from the date of delivery, simply return it to us for a full refund.

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.

The Rx-4 is capable of counting about 95% of available medications.  It can count tablets, capsules, and softgels in sizes up to 1/2″ (13mm) in diameter and 1″ (26mm) in length.  With the optional Large Pill Sensor Cover, it can count pills up to 3/4″ in diameter.  It can count any pill as small as 3mm.

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.
