Keeler Accutome- Handheld Tonometer

Keeler Accutome- Handheld Tonometer

Pocket‑Sized Precision for Instant, Reliable IOP Screening

The Keeler AccuPen™ is a lightweight, battery‑powered applanation tonometer that delivers Goldmann‑correlated intra‑ocular‑pressure measurements anywhere—exam lane, outreach clinic, ER, or bedside. Gravity‑Offset Technology, micro strain‑gauge sensors, and an auto‑averaging algorithm combine to give repeatable accuracy within ± 2 mmHg, while the rotatable, retractable probe protects the tip and streamlines infection‑control between patients.

Key Features
  • Accurate Goldmann Correlation: ± 2 mmHg agreement with Goldmann tonometry across a 5 – 60 mmHg range. Proprietary Gravity‑Offset Technology minimises positional error—no need to zero before use.
  • Fast & Easy Operation: Touch the cornea once to capture up to 9 readings in < 2 seconds; audible tone confirms each valid measurement. Large back‑lit LCD instantly displays individual values, averaged IOP, and SD.
  • Portable & Robust: Weighs only 85 g (3 oz) and measures 18.4 × 3.2 cm (7.25 × 1.25 in)—slips into a coat pocket. Probe rotates for comfortable approach, retracts fully into the housing for protection, and detaches for high‑level disinfection.
  • Long‑Life Power & Connectivity: Single 3.6 V lithium battery provides ~ 15,000 readings; easy field replacement with no charger required. Optional Bluetooth® kit lets you pre‑load patient IDs, transmit results to Keeler Connect software, or print wireless IOP reports.
  • Built‑In Quality & Safety: Factory‑calibrated; on‑board routine calibration check takes < 10 seconds. Latex‑free disposable AccuTips and a sealed keypad safeguard patients and electronics against contamination.
