The P3100 Series catalog series is assigned primarily to pressure standard products. Recorded product roles include Hydraulic Deadweight Tester. Each listing keeps its complete manufacturer part number and available specifications, so models and accessories remain separate rather than being treated as substitutes.
Within the P3100 Series series, match the complete manufacturer part number; suffixes and separators can identify a different variant.
For P3100 Series, compare the recorded Product family, Instrument class, Product part number, Manufacturer configuration fields on the individual product pages.
For P3100 Series, use the Pressure Standard title and specifications to separate complete devices from modules, accessories or replacement parts.
