China HTSY® veterinary pulse oximeter is a portable device specially designed for animal health monitoring. It can quickly and accurately measure key physiological parameters of animals, such as SpO₂, Pulse Rate (PR), Perfusion Index (PI), and Temperature (TEMP). It is suitable for various scenarios including household pets, veterinary clinics, and farms.
HTSY® veterinary pulse oximeter is a health monitoring device that integrates advanced optoelectronic sensing and signal processing technologies. Paired with a soft cuff and high-sensitivity sensor specifically designed for animals, it effectively copes with various interfering factors such as animal fur, skin pigmentation, low perfusion, and motion, ensuring stable and accurate readings even in complex usage environments.
The device features a waterproof and robust structure, equipped with a 2.8-inch color TFT display for clear and intuitive data presentation. Moreover, this product has passed relevant quality certifications, offering reliable quality for greater peace of mind during use. With its user-friendly operation and reliable data, it serves as a powerful assistant for veterinarians and pet owners. HTSY® is a domestic professional brand focused on rehabilitation and health monitoring equipment. We welcome inquiries and cooperation at any time!

The HTSY® Veterinary Pulse Oximeter is designed with an integrated adaptive motion filtering algorithm, specifically addressing the challenge of animals being unable to remain completely still during measurements. This technology effectively distinguishes between pressure noise caused by limb movement and true vascular pulse signals, significantly reducing measurement errors. Even in situations where pets exhibit slight struggling or breathing fluctuations, it ensures stable and reliable measurement results.
Since the HTSY® device offers cuffs in multiple sizes, it is suitable for animals ranging from small cats and dogs to medium-sized livestock. The cuff material is soft and breathable, conforming to the contours of the animal's limb to avoid discomfort and slippage during measurement, thereby improving compliance and measurement accuracy.
For animals in shock, under anesthesia, or with poor circulation, their peripheral blood flow signals are often extremely weak. The HTSY® Veterinary Pulse Oximeter employs a high signal-to-noise ratio sensing system and signal amplification technology to effectively capture pulse signals even under weak blood flow conditions, ensuring reliable blood pressure readings can be obtained during low perfusion. This provides crucial data support for the monitoring of critically ill animals.
A complete measurement cycle typically takes only 20 to 40 seconds. The HTSY® Veterinary Pulse Oximeter displays blood pressure values, heart rate, and pulse waveforms in real time, and features audible and visual alerts for abnormal readings. This enables veterinarians to quickly obtain information on an animal’s circulatory status during diagnosis, surgery, or recovery and make timely clinical judgments.
