The Life Support System Test Facility (LSTF) is a fully integrated laboratory system offering the capability to conduct tests at the surface and immersed in temperature controlled water to a maximum depth of up to 500msw (or deeper upon request).
Capability:
Enables precise testing to extreme conditions so design engineers can ensure the effectiveness of critical equipment.
- Diving depth control with water chilling and heating
- Breathing air heated & humidified with adjustable breaths per minute and tidal volume
- Valve cracking effort, exhale resistance and work of breathing
- Fast response gas analysis with CO2 injection and O2 dilution simulating respiration
- Hydrostatic imbalance testing of rebreathers
- Cold water chiller
- Breathing air heated & humidified
- Buoyancy Control Device Testing
Specification
- Suitable for CE marking performance tests of defence, commercial and recreational SCUBA equipment
- Verify whether equipment meets or exceeds dynamic breathing performance requirements
- Define the limits of product performance under diverse operating conditions
- Reduce costs of product testing with real time results achieved accurately and efficiently every time
- View the performance of breathing apparatus under test with real time data acquisition and display
- Large test vessel diameters up to 1000mm and internal variable orientation accommodate twin cylinder SCUBA equipment, rebreathers, diving masks, helmets, bandmasks or other equipment
- Intuitive console controls, clear computerised virtual instruments and printable test certificates
