T and D – Data Loggers – Temperature and Humidity etc

In 1986, a small group of young engineers gathered to create T&D Corporation in Matsumoto, Japan with the dream of creating, developing and producing innovative and interest-sparking products. The name of their new company was a reflection of that pioneering spirit: the T standing for TRY and the D standing for DEVELOPMENT. Of the products that they TRIED and DEVELOPED, one in particular had an incredible impact as it hit the Japanese market in 1994. This was their PC compatible compact data logger called ONDOTORI Jr. Over the past ten years these data loggers combined with other innovative loggers have continued to be an incredible success in Japan; resulting in a 90% market share. Realizing that the future of data management would be in wireless solutions, T&D has been, for the last 5 years, leading the way in providing user-friendly wireless communication loggers. By obtaining CE approval in 2003 these innovative products have been made available to a wider world market. The dreams of the small group of engineers continue today as they gain strength and breadth

TR- 7wf/nw Series – Temperature/Humidity Data Loggers – Network / USB Data Loggers

Wireless/Wired LAN Operation enables:-
· Automatic data upload to T&D WebSorage Service
· Viewing data anywhere on mobile devices and PCs
· Sending alert notifcations via email from T&D WebStorage Service

Automatic Data Upload via LAN
Equipped with a wireless LAN (TR-7wf)# and a wired LAN (TR-7nw), the TR-7wf/nw series data loggers can automatically upload recorded data to “T&D WebStorage Service” at the set interval. “T&D WebStorage Service” is a cloud service provided by T&D free of charge. It enables the viewing of uploaded data on your PC or mobile device anytime, anywhere.

Direct Wireless Communication With Mobile Devices (TR-7wf)#
T&D’s new application “T&D Thermo” enables the use of mobile devices for making/changing device settings, downloading recorded data from the TR-71wf/72wf, and viewing graph on the screen.   “T&D Thermo” is available for download free of charge.

#pending approval for use in Australia and New Zealand

USB Connection to a PC
USB operation is also possible by connecting the data logger to your computer with the USB cable.

One and a Half Years operation with just 2 batteries
Battery-powered operation means the device can be placed anywhere without the need for AC power. Depending on the settings, the TR-7wf/nw series can be used continuously for up to 1.5 years before its batteries need to be replaced.

TR-5i Series – Compact Waterproof Data Logger

The TR-5i Series includes easy-to-use waterproof compact durable loggers for measuring and recording temperature (Pt100 / Pt1000), voltage, 4-20mA, and pulse count and their low energy consumption design means longer battery life.
Collecting data is made easy with an IR enabled handheld collector for on site use or a portable USB connectable port for use with a PC.

· Infrared Interface
· Easy to Read Display
· Durable Waterproof Loggers

User Friendly Interface means: Power through Simplicity
The TR-5i Series is a family of data loggers designed to measure and record a variety of items: from temperature to pulse. The recorded data can then be easily collected with a compatible portable Data Collector or downloaded directly to a PC with a Communication Port.

Compact Design means Wider Application Possibilities
The compact size allows it to be placed almost anywhere. Also, its durable body with water- proof and dust proof capacity makes it possible to be used in harsh environments.

Low Energy Consumption Design means  Longer Battery Life
Over one year of continuous use possible. Battery replacement mark lets you know when it is time for a new battery.

Warning LED on Unit
When a set limit has been exceeded the Warning LED will fash and a message will be displayed to give you the cause.

Collect and Download Data Simple! Quick!
Via Infrared or Optical Communication
Recorded Data can be downloaded directly to a PC using a Communication Port: just connect and place logger on port. One unit of full data can be downloaded in just 25 seconds!


On-site Data  Collection On-the-spot Data  Checking
Data collection via IR communica- tion makes it possible to collect recorded data without ever having to move or touch the logger. The collected data can then be checked there on the spot…no need for a PC.
