What T&D does
T&D Corporation is a Japanese specialist manufacturer of wireless data loggers, headquartered in Matsumoto-City, Japan, and founded in 1986. The company designs and sells stand-alone hardware loggers that measure temperature, humidity, CO2 concentration, illuminance/UV, barometric pressure, voltage, 4-20mA current, and pulse count. Its product portfolio is organized into multiple active series (RTR500B, TR7, TR4A, TR-5i, TR-7Ui, RTR-600, MCR, TR32B) spanning Bluetooth, USB, wireless radio (up to 150m range), and network-connected base stations (RTR500BW for LAN, RTR500BM for 4G mobile, RTR500BC for wireless USB). A discontinued RTR-500 series remains backward-compatible with the current RTR500B line, preserving the installed base.
The company's technology platform pairs the hardware with a free, unlimited cloud-based T&D WebStorage Service that supports real-time monitoring, graph visualization, threshold-based warning notifications, and a documented public API. Supporting software is free of charge: Windows applications (RTR500BC for Windows, T&D Graph, T&D Tools, T&D Data Server, Adjustment Tools, CO2 Recorder, Illuminance UV Recorder) and mobile apps for iOS and Android (T&D Thermo, ThermoREC, ThermoStorage, T&D 500B Utility, TR4 Report). Notable technical features include OAuth 2.0 support for Microsoft Exchange Online email alerts, FTP server auto-upload, and battery life up to four years on certain models.
T&D's business model is hardware-led with a freemium cloud/software layer. Revenue is generated primarily through sale of data logger units and accessories via a distributor network spanning more than 60 countries; pricing is not publicly disclosed and customers are directed to regional distributors for quotes. The company serves six core verticals — healthcare/pharmaceutical (including CDC VFC vaccine compliance), food industry (HACCP), museums/archives, research and academia, facilities management, and construction — with named customers ranging from Saint Louis Art Museum and Central Japan International Airport to NASA Space Shuttle Atlantis. Marketing is conducted through the company website (tandd.com), regional social media accounts for US and EU, the Ondotorism blog, case-study usage reports, and active participation in vertical trade shows (AHR Expo, IAFP, AIC, Society of American Archivists, PCI Days, LabsExpo).
