DPM4 Parameter Tester is a highly accurate meter for testing a wide range of medical devices. Key features include its lightweight, compact size and battery operation.

The DPM4 is available in four models: 1H, 1G, 2H, and 2G. The DPM4-1G is the replacement for the popular, but now obsolete DPM3. Basic parameters cover pressure, vacuum, and temperature measurements (Models 1H and 1G). Gas flow, barometric pressure and humidity measurements are included in the enhanced Tester (Models 2H and 2G). The Tester is menu-driven and simple to operate. All functions are set from a 128 x 32 pixel graphical display

DPM4 is ideal for the testing done as part of preventive maintenance or repair processes whenever measurement of pressure, flow, or relative humidity is required.

Features
