Condition & Warranty
Used. This Tono-Pen VET has been fully tested and is in excellent working order. The micro-electronic strain gauge mechanism reads pressure accurately, the digital LCD display shows clear segments, and the activation button responds instantly. The transducer tip is clean and uncompromised. Minor cosmetic wear consistent with a field-used clinical instrument. Covered by a 90-day warranty on parts and workmanship.
Tono-Pen VET — Used Veterinary Applanation Tonometer
The Medtronic Tono-Pen VET is the globally recognized handheld standard for measuring intraocular pressure (IOP) in veterinary patients. Engineered with highly sensitive micro-electronic strain gauge technology, this tono-pen vet converts mechanical applanation force directly into an objective digital pressure reading. Unlike human tonometers that can yield skewed data due to species-specific scleral rigidity differences, the Tono-Pen VET is internally calibrated for animal corneas — delivering consistent, reliable IOP readings across dogs, cats, horses, and exotic species.
Designed to minimize animal stress and enhance diagnostic speed, this tono-pen vet features an automated processing engine that takes multiple rapid readings per eye and displays a finalized, statistically averaged IOP value alongside a statistical variance indicator. Its lightweight, battery-powered form factor allows practitioners to perform pressure checks in any environment — including the exam cage, field visits, or mobile clinics — without cumbersome setup or external power requirements.
Research published in the National Library of Medicine confirms that the Tono-Pen Vet tonometer provides clinically accurate intraocular pressure measurements in both normal cats and cats with glaucoma, validating its use as a primary diagnostic instrument in small-animal ophthalmology practices.
Why Practices Choose the Tono-Pen VET
- Veterinary-Specific Calibration — Internally programmed to account for the unique structural properties of animal corneas, eliminating manual conversion charts and reducing species-specific measurement error
- Automated Multi-Reading Averaging — Automatically compiles and averages consecutive valid measurements while displaying a statistical confidence indicator to filter out animal motion artifacts
- Ultra-Portable Handheld Design — Ergonomic, battery-powered body fits easily into a pocket or storage case, enabling pressure checks in any position or clinical environment
- Gentle Applanation Profile — Minimizes the corneal contact surface area, reducing animal anxiety and the need for deep sedation during routine IOP checks
- Hard Shell Protective Case — Durable, fitted hard-shell carry case safeguards the micro-electronics and delicate transducer tip between patient runs
- Instant Digital LCD Display — Large, easy-to-read numeric display presents immediate pressure readings and the variance indicator, speeding diagnostics in busy multi-species practices
- Proven Clinical Durability — Solid-state electronics inside a ruggedized housing prevent calibration drift under heavy daily usage in general practice and specialty environments
Clinical Applications
- Canine Glaucoma Screening and Monitoring — Routine IOP checks in high-risk breeds (Basset Hound, Cocker Spaniel, Chow Chow) to detect elevated pressure before irreversible optic nerve damage
- Acute Uveitis Diagnostics — Low IOP readings serve as a vital early indicator of active intraocular inflammation in cats and dogs
- Emergency Eye Trauma Assessment — Rapid baseline IOP checks for anterior chamber flattening, hypotony, or intraocular hemorrhage in urgent-care settings
- Equine and Exotic Ophthalmology — Handheld flexibility allows pressure assessment on horses, rabbits, ferrets, and other non-standard species without a fixed lane setup
- Post-Surgical Monitoring — Tracks IOP recovery after cataract surgery, cyclodestructive procedures, or aqueous shunt placement in veterinary patients
Who This Is For
- General Veterinary Practitioners adding essential glaucoma screening to their everyday diagnostic suite without investing in a tabletop tonometry system
- Emergency Veterinary Hospitals requiring a rapid-use, self-contained instrument for after-hours trauma and urgent ocular evaluations
- Veterinary Ophthalmologists and Specialists seeking a reliable, field-tested mobile standard for auxiliary lane checks, off-site equine visits, and specialty referral clinics
