DHP 145 Leakage Test System
Computer-controlled leakage test system for components and devices, measuring leak rate as a function of pressure in overpressure or vacuum operation across a wide test-air temperature range.
Model Overview
| Model | System purpose | Standards / method | Core fit |
|---|---|---|---|
| DHP 145 | Pressure- and suction-mode leak testing with direct pressure measurement at the test specimen | Application-specific leak-test methods | Tightness testing of technical components and devices under controlled pressure and temperature conditions |
Key Features
Overpressure and vacuum testing
Supports both pressure and suction modes for a broad range of component-leakage tasks.
Direct specimen pressure measurement
Measures test pressure directly at the connected test object for representative results.
Wide leak-flow range
Cascaded laminar-flow elements cover test flows from 0.005 to 300 L/min.
Extended temperature operation
Handles test air from -40 to 120 °C while protecting measurement instrumentation through heat exchange.
Remote specimen connection
Two-metre connection lines allow the specimen to remain inside a climatic chamber during testing.
Automated DHPWin operation
PC-based software guides test sequences, captures data and supports repeatable evaluation.
