SENSOR HIGHLIGHTS
Respiratory Equipment
Devices used in critical respiratory care require reliable oxygen (O₂) monitoring to protect patients and support clinical decision-making. Accurate real-time oxygen concentration measurement ensures patients receive prescribed oxygen levels and prevents complications caused by hypoxia or hyperoxia.
Optimized specifically for non-anesthetic medical ventilators, our medical oxygen sensors deliver stable and repeatable responses required for respiratory devices, facilitating optimal clinical outcomes.

Oxygen & Oxygen Concentrators
Oxygen (O₂) is an essential gas in medical applications. Non-invasive diagnosis via exhaled oxygen detection assists in assessing human metabolism. Precise oxygen monitoring is critical for both short-term and long-term use of oxygen concentrators. Whether for hospital respiratory care or home-based chronic disease management, accurate oxygen measurement guarantees effective patient treatment.
Our medical oxygen sensors feature reliable readings, rapid response and long-term stability to ensure dependable performance for patients and equipment.

Digestive Analysis (SIBO)
Growing awareness of digestive disorders and intestinal health has boosted the adoption of breath tests, a rapid and accurate method to evaluate patients’ digestive function.
Hydrogen (H₂) levels in exhaled breath serve as a key biomarker for lactose intolerance, Small Intestinal Bacterial Overgrowth (SIBO) and carbohydrate malabsorption. Therefore, high detection accuracy is fundamental to effective diagnosis and treatment planning.
SENSOR HIGHLIGHTS
Medical Infrastructure
Monitoring potentially hazardous gases in medical facilities and systems is vital to safeguard hospital staff and patients.
Modern medical treatment and decontamination processes frequently use gases such as ozone (O₃) and ethylene oxide (ETO). There is a rising demand for gas leakage monitoring in medical premises to prevent excessive gas exposure and ensure safe re-entry after decontamination cycles.
