Accurate
The VT650 Gas Flow Analyzer offers high accuracy and reliability for gas flow and respiratory medical equipment, including neonatal, mechanical and high-frequency ventilators. The single, full range ±300 lpm air flow channel offers built-in oxygen, temperature and humidity measurements to streamline your testing procedure. Designed and tested to world renown Molbloc-L calibration specifications ensures traceability to global regulatory standards with measurements you can rely on.

Portable
Everything you need to perform tests is included in the VT650 – no extra modules or components are required. Weighing only 3.6 lb (1.6 kg), this compact, all-in-one device is highly portable. The snap-in carrying handle/shoulder strap, small unit size, and rugged design allows you to quickly and easily test on-the-go. With AC and DC power options and an 8-hour battery life, this tester is perfect for both clinical and field environments where AC power may not be available, but high accuracy is needed.

Easy-to-use
The VT650 has a large 7 (17.8 cm) touch screen display, allowing you to view multiple measurements at once and quickly access menu options. Review results in real-time with either color graphs or numerical data. The global user interface makes operating this device straightforward and uncomplicated.

Traceable
The large onboard memory allows testing of multiple medical devices back-to-back without having to transfer data off between tests. Record and store test data, save time and streamline your testing needs by creating customized test profiles. When you are finished with your testing, simply save and transfer the data via USB to a PC and upload the test file to your CMMS for easy documenting and reporting.
