Ametek R-100 Mansfield & Green Deadweight Pressure Tester 5lbs to 10,000lbs

Current Stock:

Product Description

Manufacturer: Ametek

Model: R-100

Condition: Used. Comes in non-original packaging. This lot is in Fair cosmetic condition, with lots of minor scuffs/scratches from prior use.  There is a bit of oil all over most of the tester parts.  The instruction manual (not shown) is completely soaked in oil.  The cases have adhesive tape residue on them from previous attempts to tape them closed, as well as scuffs and scratches all over.  The gauge is one we had bouncing around the shelves and it has a cracked crystal but still works. The photos show the exact item(s) the buyer will receive.

Notes: This set is in Good working condition.  We were able to make measurements on both ranges (see last 2 images) with no difficulty.  High and low volume settings on the pump both work.  No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
