Instrument Exchange · Part of Source at Obsidian Dynamics
Obsolete instrument?
We'll help you find it.
Specialist sourcing for discontinued and difficult-to-find pressure, flow, calibration and process instrumentation. Send manufacturer and model or part number; we investigate suitable supply options.
Identity first. Duty second.
If you know the manufacturer and the model or part number, send those — that is this desk. We investigate discontinued and difficult process, pressure, flow and calibration instruments one requirement at a time.
If the original cannot be found and an alternative is acceptable, say what the instrument has to do: range, medium, output, process connection, and the failure you are trying to avoid. A like-for-like replacement and a workable alternative are not the same search. For application-led alternatives, start on Send a requirement.
Instrument Exchange is the obsolete-parts desk inside Source, and works across both Inspect (NDT and inspection) and Maintain (maintenance and reliability). Current equipment, where the application matters more than a legacy part number, starts on Source.
Enquiry
Send manufacturer + model/PN
Start with the manufacturer and the model or part number. The next screen adds your email and an optional nameplate photo, then sends it to us in one go.
What we source
The families we are asked to locate.
Brand names below are examples of what we can try to source and locate — not inventory on hand.
Deadweight testers
Primary pressure standards, including examples such as Budenberg and DH-Budenberg testers.
Process calibrators
Multifunction and documenting calibrators, including examples such as Beamex MC5 and Fluke 744 / 743B.
Flow & process
Selected flow and process instruments for installed-base life-extension, including examples such as Siemens SITRANS.
How it works
Send. Source. Verify. Supply.
01
Send
Manufacturer and model, or a part number, plus the short requirement. Quantity, range and deadline help.
02
Source
We investigate suitable supply options through specialist channels. Availability is never assumed.
03
Verify
We check identity, condition class and obvious configuration before any quote.
04
Supply
When a unit can be secured, we arrange supply on the agreed condition class.
The brief
Difficult is the point.
This desk exists for discontinued, obsolete and awkward-to-find instrumentation — not for items you can order from a current catalogue. If the model is still freely available, say so; we will tell you when a standard channel is the better route.
We source and locate. We do not publish prices without a sourcing conversation, and we do not guarantee availability.
Calibration
Obsidian is not UKAS-accredited.
Optional calibration is arranged through a third-party laboratory. If you need a UKAS-accredited certificate, say so on the enquiry — the form labels that option as "UKAS via third-party laboratory", not as an Obsidian accreditation.
We do not operate a calibration laboratory and we do not present third-party certificates as our own.
Why Obsidian
A specialist sourcing desk, not a stock catalogue.
