APMi Intrinsically Safe Pressure Module

Brand: Crystal Engineering by Ametek

Intrinsically Safe Pressure Module

The APMi intrinsically safe portable pressure modules offer the functionality and flexibility to read up to four pressure inputs with a single HPC50 handheld pressure calibrator.

Use the modules to either expand the range of the HPC50, view all four readings at the same time, or read two different differential pressures simultaneously.

The APMi intrinsically safe pressure modules deliver the same high level accuracy whether in the lab or in the field.
