Our innovative and cost-effective test lungs safely test ventilators and anesthesia machines for function and precision. Variable patient parameters such as resistance, compliance or airway leakage can all be adjusted independently. Both SmartLung and EasyLung are extremely handy and user-friendly.
Accurate oxygen concentration measurement is essential for verifying and calibrating respiratory devices, ventilators, and other medical equipment.
The CITREX H3 offers an optional oxygen sensor that can be integrated into new equipment or added later as a retrofit kit. This sensor measures oxygen concentration in the flow channel, eliminating the need for additional modules.
The H3 measurement method offers highly accurate bidirectional flow, volume, and pressure measurements with minimal flow resistance.
The CITREX H3 ventilator tester measures and displays 16 different ventilation parameters. The color screen displays pressure, volume, and flow parameters in real-time.
Users can easily configure these parameters and their units using the integrated web server or directly on the CITREX H3.
Up to five gas types and nine gas standards allow for a wide range of applications in medical devices.
Annual calibration of your CITREX H3 is crucial to ensure precise measurements. Take advantage of our hassle-free EasyCal calibration service to arrange pick-up, generate shipment and customs papers online, and preserve the accuracy of your gas flow and pressure measuring device.
EasyCal provides annual maintenance, software updates, and sensor adjustments to guarantee long-term precision. It is the easiest and most reliable way to keep your device in top condition.
