Can we help you?

The RTR-500/RTR500B series allows you to combine a range of wireless radio communication loggers with various data collectors to meet your needs.

The RTR500BM is a data collector equipped with 4G mobile network capability. It collects data from nearby data loggers via wireless radio communication, then automatically sends it via a 4G cellular network* to the free "T&D WebStorage Service" cloud storage service for anytime, anywhere access.

The RTR500BM also has a warning monitoring feature that sends a warning email via the T&D WebStorage Service when a set limit is exceeded.

It's perfect for situations where you don't have a PC or LOCAL NETWORK available, such as during transport, in greenhouses or on construction sites. As long as you can provide power, you can collect and transfer data without worry or stress.

*A SIM card is required. Some carriers in the US are not supported and cannot be used with the RTR500BM. Please contact your T&D distributor for details. For more information on carriers in other countries, contact your local T&D distributor.

The RTR500BM can be combined with any of our RTR-500/RTR500B series data loggers. And up to 20 loggers can be registered for simultaneous use. Use our PC software “RTR500BM for Windows” or the mobile app “T&D 500B Utility” to make mobile communication settings.

Because it uses mobile networking to transfer data, all you need to do is secure a power source and be in mobile range in order to send data to our cloud-based "T&D WebStorage Service" which makes it easy to check data, display graphs, and check warnings from your PC, smartphone or tablet anytime, anywhere.

Upon a warning, notification can automatically be sent via e-mail from T&D WebStoarge Service and/or by connecting a buzzer or lamp to the contact output, you can set up an on-site alarm.

*1: RTR-500 Series loggers and Repeaters do not have Bluetooth capability.

*2: When using RTR500BC as Repeater. Depending upon conditions it may take up to an additional 2 minutes.

*3: In order to use the external terminal, please purchase the optional alarm connection cable (AC0101).

*4: Client Function

*5: Battery life depends on several factors, including number of warning reports sent, ambient temperature, radio environment, frequency of communication, and quality of the battery being used. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life.

*6: In order to use the GPS function (to attach geographical positioning info to current readings data),please purchase a compatible GPS antenna (SMA Male Plug).

*7: Please prepare a contracted SIM card (with a minimum speed of 200Kbps) separately.
