STEMart adds dissolved oxygen meters for lab and industrial use

STEMart has expanded its testing and measurement lineup with dissolved oxygen meters for laboratory, environmental, aquaculture, wastewater and pharmaceutical applications. The new instruments are aimed at faster, more accurate water-quality monitoring across research and industrial settings.

Why it matters: - Dissolved oxygen measurement is a core water-quality test that affects marine life, drinking water taste, corrosion risk and wastewater performance. - The new meters are aimed at labs and industrial users that need real-time monitoring and repeatable results across different sample conditions. - The product line broadens STEMart’s testing and measurement offerings for medical device development and related technical work.

What happened: - STEMart announced high-precision dissolved oxygen meters as part of an expanded testing and measurement portfolio. - The new instruments are intended for laboratory, environmental, aquaculture, wastewater, water-quality and pharmaceutical manufacturing applications. - STEMart is a U.S.-based provider of services and technical solutions for medical device development.

The details: - Dissolved oxygen meters use electrochemical, polarographic, amperometric, galvanic or optical sensors to measure oxygen content in water or solutions. - The measurements help assess water quality and verify oxygen supply systems in reactors and wastewater treatment facilities. - Common use cases include groundwater remediation, wastewater treatment, aquariums and fish hatcheries. - STEMart says the new series supports reliable real-time monitoring and options for different measurement requirements, sampling environments and industry standards. - The LC-DO-3S benchtop meter is designed to measure dissolved oxygen and temperature in aqueous solutions. - The LC-DO-3S includes a 6.5-inch white backlit LCD display, tactile keys and a built-in microprocessor for automatic calibration, data storage, parameter settings and data export. - The LC-DO-3S uses a polarographic electrode with an integrated temperature sensor for automatic temperature compensation. - The LC-DO-3S includes manual salinity and atmospheric pressure compensation functions. - The LC-DO-3S uses digital filtering and sliding differential processing to improve response speed and reading stability. - The LC-DO-3S electrode requires 3–5 minutes for polarisation and uses a snap-on membrane cap. - The LC-DO-3S can store up to 2,000 measurement results and transfer data via USB, Bluetooth printer or a compatible mobile app. - The NOS-100 Dissolved Oxygen Sensor is a compact handheld device for measuring dissolved oxygen. - The NOS-100 uses a stainless steel probe and is suitable for portable and benchtop use. - The NOS-100 supports automatic and manual modes and is positioned for water sampling and water column profiling. - The NOS-100 is intended for aquaculture, environmental monitoring and natural science applications. - More information is available in STEMart’s dissolved oxygen meter category.

Between the lines: - STEMart is targeting buyers that need both bench-based precision and field-ready portability in one product category. - The emphasis on compensation features, digital filtering and data export suggests a focus on usability in mixed or variable water conditions. - The lineup also signals demand for instruments that can bridge research, compliance and operational monitoring.

What’s next: - STEMart is directing customers to review available models, specifications and configurations online. - Further adoption will likely depend on how the meters fit existing lab workflows, sampling needs and monitoring budgets.

The bottom line: - STEMart is expanding into dissolved oxygen measurement with two new instruments designed to serve both laboratory users and industrial water-quality applications.
