Meet VentiTest

Self-contained, wireless ventilator testing with touchscreen

VENTITEST is an innovative multi-path digital ultrasonic ventilator calibration solution. The integrated touch-screen and high capacity Lithium-ion battery allows for standalone operation and quick on-site testing for validation of ventilator outputs, while the VENTITEST-S (PC software) provides data logging, highly detailed data display, customizable flow, volume, pressure charts and reporting of results

Ultrasonic technology

The new standard in ventilator calibration

Digital ultrasound provides the most accurate and simple method for sensing pressure and flow, and therefore for calibrating ventilators.
Digital ultrasound has a resolution in the order of 2.5% for pressure and flow measurement, and the technology requires minimal calibration. Additionally the flow through tube of the VENTITEST has minimal flow impedance and is therefore improving efficiency and accuracy.
