Is now a good time to switch to simplified, low-cost equipment for your quality control needs?
TecSense GmbH has launched the SGA series, a line of handheld devices utilizing optochemical technology to measure oxygen levels across various industrial environments. The series serves as an economical alternative to the existing TEC-PEN line for users prioritizing mobility and precision.
Why it matters
By offering a lightweight and cost-effective solution, the series provides professionals with a portable way to maintain rigorous quality control in fluid, packaging, and welding workflows. The devices are designed to replace more expensive equipment while maintaining high-resolution monitoring capabilities.
The SGA series utilizes optochemical sensing technology and offloads data management to external computers instead of onboard storage. The Fluid model measures 0 to 2000 ppb with 1 ppb resolution, while the MAP unit covers 0 to 5 percent at 0.001 percent resolution.

Timeline
The official article regarding the SGA series was published on October 25, 2026.
The Tech Race
The release of the SGA series represents a strategic shift toward specialized, lightweight optochemical tools that replace legacy, higher-cost handheld sensors. This transition mirrors a broader trend in industrial instrumentation toward cost-efficient, mobile-first hardware.
Industrial users can expect a simplified workflow with the one-button interface and reduced equipment weight during site inspections. Because the devices rely on computer-managed data, operators will need to ensure they have appropriate software interfaces ready to record readings.
The takeaway
These handheld sensors offer a streamlined alternative for field professionals requiring high-resolution oxygen monitoring without the bulk of traditional units. Users should prioritize integrating these sensors into existing computer-managed data workflows to ensure accurate logging of industrial measurements.
