Since their beginnings in 1986, T&D has been committed to being the most trusted name in the data logger industry. The company remains at the forefront of innovation, which now includes meeting customer’s demand for “anytime anywhere access” to data.
Interview with Minoru Ito from T&D Corporation, Head of the European Sales Office.
Monitoring environmental conditions like temperature and humidity is crucial across many industries. Can you tell us how T&D approaches this challenge?
Minoru Ito: Absolutely. At T&D, we understand that precise and reliable data is the backbone of quality control, compliance, and operational efficiency. That’s why we’ve developed the RTR500B series – a comprehensive, wireless solution for data logging. It’s specifically designed to make environmental monitoring easier, more accurate, and adaptable to a wide range of use cases.
For the food industry, safety is a major concern, especially with regulations like HACCP in place. How does the RTR500B series support companies in meeting these strict requirements?
M.I: Great question. HACCP (Hazard Analysis and Critical Control Points) regulations demand accurate, continuous, and tamper-proof documentation of critical parameters such as temperature. Even the slightest deviation can compromise food safety and lead to regulatory violations. The RTR500B series helps food industry professionals meet these demands by providing automated, error-free data logging and real-time monitoring. The data is securely stored, can be backed up in the cloud, and is accessible anytime for audits or compliance reports. This eliminates manual errors and ensures traceability, which is exactly what HACCP compliance requires.
What sets the RTR500B series apart from other data logging solutions on the market?
M.I: The RTR500B series stands out for its wireless communication capabilities, which eliminate the need for complicated cabling. It can transmit data over distances of up to 150 meters, and with repeaters, that range can be extended even further. This gives our customers significant flexibility when deploying loggers across warehouses, laboratories, cold storage facilities, or medical sites.

What types of data can users collect with this series?
M.I: The RTR500B series is compatible with a wide range of sensors. You can measure temperature, humidity, illuminance, UV intensity, CO concentration, voltage, current (4 – 20 mA), and even pulse signals. This versatility makes it suitable for everything from cold chain logistics to pharmaceutical manufacturing and research labs.
How is the collected data managed and accessed?
M.I: One of the major advantages is integration with our free T&D WebStorage Service, a cloud-based platform. This allows users to automatically back up their data and monitor it remotely via any internet-connected device. It simplifies the whole process – there’s no need for manual downloads or PC-based analysis. Plus, our system supports multiple base units like the RTR-500BC (USB), RTR-500BW (WLAN or Wired LAN), and the RTR500BM (4G), which can serve as central hubs for data collection and alerting.
What types of environments is the RTR500B series best suited for?
M.I: We’ve seen it successfully deployed in logistics, cold chain management, hospital, blood bank, laboratory and warehouses settings. Its wireless architecture and sensor variety make it ideal for any setting where constant, accurate monitoring is essential.

Why do customers choose the RTR500B series specifically?
M.I: Customers appreciate the plug-and-play setup, the flexibility to customize based on application, and the reliability of both the hardware and the cloud system. Our devices are built for long-term use, and the system offers features like automatic alerts and secure data storage that help users react quickly to any anomalies.
It sounds like T&D has created a very forward-thinking system.
M.I: That’s our goal – to provide intelligent, seamless solutions that reduce manual work and improve accuracy. The RTR500B series exemplifies that approach. Whether you’re monitoring a cold storage or a distribution center, it delivers the peace of mind that only real-time, wireless precision can offer.

T&D has clearly established itself as a leader in data logging solutions. Is the company currently expanding its presence in Europe?
M.I: Yes, absolutely. T&D is in a phase of continuous growth, and Europe is a key focus for us. We’re actively looking for qualified distributors throughout the continent who are interested in partnering with us to bring our RTR500B series – and other solutions – to new markets. We value partnerships with companies that understand the importance of reliable measurement technology and have strong connections in sectors like pharmaceuticals, food logistics, healthcare, or industrial automation. Our distributors benefit from competitive products, robust technical support, and the strength of a globally trusted brand.
