Features
l The instrument uses a gas source that can provide (20 ± 1) kPa pressure to continuously pressurize the sample without being limited by the space of the test site.
l The instrument has a pressure gauge to display the pressure, the pressure can be adjusted.
l Use pressurized medium: compressed air.
l The special stainless steel penetrating test slot ensures that the sample is firmly clamped, and the synthetic blood is prevented from splashing around.
l Square metal barrier net: open space ≥50%; bending ≤5mm at 20kPa.
l Digital display timer, accuracy ± 1 second.
l The instrument has a clamp that can generate 13.5Nm torque.
