Technology & Products
Key Products
Oxygen Analyzers (Sil-O2, Minox i, SenzTx transmitters); Nitrogen Blanketing Systems; Fluid Measurement Instruments; Process Monitoring Sensors; Integrated AM Process Control Solutions
Technological Advantage
Proprietary oxygen sensor technology (Sil-O2 analyzer, Minox i transmitter) with integration capability for AM powder bed fusion systems; bundled measurement suite reduces customer need for multi-vendor solutions; established relationships with AM equipment OEMs and end-users across aerospace/defense.
Differentiation
Value Proposition
Integrated oxygen detection and nitrogen blanketing solutions reduce fire risk in solvent-based additive manufacturing processes, ensure powder atmosphere integrity in metal AM systems, and provide real-time monitoring for process optimization—lowering scrap rates and improving repeatability in critical aerospace and defense applications.
How They Differentiate
Focused measurement suite for critical powder atmosphere parameters (oxygen, nitrogen blanketing, fluid composition) rather than broad AM software platforms; decades of industrial instrumentation heritage; integrated portfolio across multiple sensing modalities.
Market & Competition
Target Customers
AM equipment manufacturers, metal powder bed fusion operators, aerospace/defense manufacturers using AM
Industry Verticals
Additive Manufacturing (metal powder bed fusion); Aerospace & Defense; Chemical & Oil/Gas; Pharmaceuticals; Food Processing; Environmental Monitoring
Competitors
Instrument manufacturers specializing in oxygen measurement (PreSens Precision Sensing, other industrial gas analyzers); Broader AM process control systems providers (Siemens, Dassault); In-situ AM monitoring specialists (Melt Pool Imaging, other thermal/optical monitors)
Growth & Milestones
Growth Metrics
Established PST as global, scaled market leader post-2020 AEA investment; expanded North American presence; added complementary sensor portfolio companies (FCI, Sensore) to expand measurement capabilities for demanding industries including AM.
Major Milestones
Founded 1964 (PST Ltd, UK); 2019: Acquired Ntron Ltd; 2020: AEA Investors and Battery Ventures majority investment; 2023: Acquired FCI (Fluid Components International) and Sensore Electronic GmbH; November 2024: Acquired by DwyerOmega (Arcline Investment Management portfolio)
Notable Customers
Major aerospace & defense manufacturers (implied by aerospace/defense industry focus); Metal powder bed fusion equipment makers (integration partners)
