Enduring relationships with businesses across Japan have supported Testo’s development from a supplier of handheld instruments to a measurement technology and service partner. The German company values the trust placed in its equipment, expertise and support.

“Japan is a highly valued market that places the most exceptional value on accuracy, reliability and long-term partnerships,” Testo CEO Eckhard Kloth said.
Testo SE & Co. KGaA supplies instruments, monitoring systems and services that measure temperature, humidity, emissions and other environmental conditions. Contractors use its equipment to check heating systems, food producers to help maintain safety, and pharmaceutical businesses to monitor production conditions. Industrial operators apply the data to improve processes and conserve resources.
Founded in Germany in 1957 and headquartered in Titisee in the Black Forest, Testo established its Japanese subsidiary in Yokohama in 1987. The group’s 70th anniversary and the subsidiary’s 40th anniversary coincide in 2027.

The milestones recognize the businesses that rely on Testo, together with the partners and employees who support its presence in Japan. Testo is preparing for emerging needs through investment in digital technologies and services, with continued attention to service quality.
“Customers increasingly want real-time visibility into critical environmental conditions rather than isolated measurements at scheduled intervals,” Kloth noted.
Pharmaceutical, healthcare and food businesses require automated monitoring and digital documentation to support compliance and reduce manual workloads. Accessible, traceable records make information easier to incorporate into operations, meeting expectations for integrated systems.

Property owners and industrial operators are collecting data on indoor climate, energy consumption and emissions to improve efficiency and pursue environmental targets. Cloud monitoring and data analysis are becoming important to this work. “Measurement data becomes increasingly valuable when it can be connected, analyzed and transformed into actionable insights,” Kloth explained.
Testo invests about 10% of its revenue into research and development. The group has 37 subsidiaries and over 80 trade partners, giving its Japanese operations access to international resources. “Japan continues to be a highly admired global leader in advanced manufacturing, automation and quality management,” Kloth said.
Technical exchanges between the German and Japanese teams combine expertise in sensors, metrology and digital services with market knowledge. Insights from the industries Testo serves inform the development of applications suited to their requirements. Sharing that experience throughout the group enables Testo to apply insights from Japan to technical challenges in other markets.
