Ashcroft
Ashcroft builds pressure instrumentation, and products here include pressure modules, gauge comparators, deadweight testers and loop calibrators, some carrying the Heise name for the digital gauge line.
Ashcroft and Heise appear together on several part numbers in this catalogue because Heise is Ashcroft’s precision digital gauge brand. Modules are matched to the base readout, so confirm which instrument you own before selecting ranges, and check whether you need gauge, absolute or differential reference, since substituting one produces a consistent offset rather than an obvious fault.
