The DL-3004P / DL-3004H Pneumatic Pressure Tester is a precision laboratory instrument designed for evaluating material resistance under controlled pressure. The DL-3004P measures up to 1 MPa, while the DL-3004H measures up to 2 MPa. Both models feature air clamps, an LCD touch panel controller, and standard test bells (7.3–50 cm²), with optional larger sizes available. Equipped with a rubber membrane (Ø80mm, 0.9mm thick) and maximum distension of 70mm, the system allows pressurization at 100–500 ml/min. Output is provided via a record printer, and the units are powered by 220VAC single-phase (200W). Ideal for accurate and reliable pressure testing in laboratories.
