What Lear Siegler Australasia does

Lear Siegler Australasia Pty Ltd is a privately held Australian company specialising in the distribution, integration, and servicing of environmental and process monitoring equipment for the Australian and New Zealand markets. The company sources specialist instruments from international manufacturers including Thermo Fisher Scientific, Nippon Instruments, Environics, XSENS, Envitech, and SK-Elektronik, then provides local sales, installation, commissioning, calibration, repair, and maintenance services through a three-office network spanning Mount Waverley VIC (headquarters), Caringbah NSW, and Canning Vale WA. Its customer base spans government environmental agencies and EPAs, mining operators, power generation and petrochemical facilities, and oil and gas operations.

The company's technical portfolio is anchored in TEOM (Tapered Element Oscillating Microbalance) continuous mass-based particulate measurement, beta attenuation monitoring, gas analysis (NOx, SO2, CO, O3, CO2, N2O, hydrocarbons), atomic fluorescence mercury detection, and clamp-on ultrasonic flow and water cut measurement. A NATA 17025 accredited laboratory and field service capability enables the company to issue calibration certificates traceable to Australian Standards, which is a regulatory requirement for compliance-grade monitoring in mining dust (AS2985) and emissions applications. The business also develops and supports data acquisition software (Envidas, Envista ARM) used to log and report monitoring data.

Commercially, Lear Siegler operates a sales-led go-to-market with quote-based pricing across all offerings, supported by experienced service engineers who provide pre-sales technical consulting and post-sales support. The company is family-led, with Peter Phaedonos as Managing Director and Nicholas Phaedonos as Director, and has remained privately held since 1982. The company generates revenue through equipment sales, calibration services, repair, managed maintenance contracts, installation and commissioning, and bespoke R&D for customer-specific protocol development.

Core offering

Lear Siegler Australasia distributes and integrates environmental and process monitoring equipment for the Australia and New Zealand markets, sourcing instruments from global manufacturers (Thermo Fisher Scientific, Nippon Instruments, XSENS, Environics, Perma Pure, SK-Elektronik). The company provides turnkey solutions combining equipment supply with installation, commissioning, calibration, repair, maintenance, and R&D services, supporting particulate, gas, mercury, flow, and combustion monitoring applications.

Product overview

Lear Siegler Australasia is a specialized distributor and integrator of environmental and process monitoring equipment, not a software platform company. The company offers a comprehensive portfolio of monitoring instruments organized across several product categories: Particulate Matter Monitors (including TEOM-based monitors like the 1405 series, Beta Attenuation Monitors such as the 5014i and 5028i, SHARP hybrid monitors, Personal Dust Monitors like the PDM 3700, and various samplers including Partisol and MiniVol); Gas Analyzers (Thermo Fisher series for measuring O3, CO, CO2, NO/NO2/NOx, SO2, N2O, THC, and multi-gas configurations); Mercury Analyzers (Nippon Instruments thermal decomposition and atomic fluorescence analyzers for atmospheric and laboratory applications); Flow and Water Measurement equipment (XSENS clamp-on ultrasonic meters for flow rate and water cut measurement); Combustion and Flammability analyzers (Enerac combustion efficiency analyzers and PrevEx flammability monitors); Sample Conditioning systems (Perma Pure gas dryers and humidifiers using Nafion technology); and Data Acquisition Software (Envidas and Envista ARM platforms). The company also provides integration, installation, commissioning, calibration, repair, and maintenance services. These products are sourced from international manufacturers including Thermo Fisher Scientific, Nippon Instruments, Environics, Envitech, XSENS, Perma Pure, SK-Elektronik, and others, then integrated and supported by Lear Siegler for the Australian and New Zealand markets.
