HORIBA checks gas flow by weighing it
HORIBA supplies analytical and measurement equipment to vehicle and semiconductor manufacturers, healthcare providers and research institutions. In semiconductor production, its devices control the flow of gases and liquids entering manufacturing equipment.
From a measurement reference to process control
A flow reference built from changes in mass
Measurement for calibration
A semiconductor maker’s process tool
Use the measurement to calibrate a chain of reference instruments
Left: the calibration principle. Right: a product application. They are separate installations, not one connected gas line. The drawing does not put a balance inside the product or imply that every product is measured directly on this system.
Calibration equipment has a processing capacity, too
R&D spending rose in a year of sales growth
Group spending on research and development

The work of checking flow, and its cost
Read the calibration principle, the customer’s process and development spending separately.
- Measurement referenceDerive flow from mass and time, then calibrate reference instruments
- Customer productionControl material flow into deposition, etching and other processes
- Research and developmentExpand calibration and testing capabilities and develop technology
THE VIEW AFTER THE NUMBERS
What the numbers suggest
HORIBA checks gas flow by tracing it back to mass and time, then uses that reference for calibration. Behind the compact controllers supplied to semiconductor manufacturers are measurement facilities that manage vacuum conditions, temperature and vibration.
In FY2025, Materials & Semiconductor sales grew while accelerated R&D and technology investment contributed to lower operating income. HORIBA sells devices that control flow and develops the means to verify that flow.
