RTR-5 and RTR-7 Series Wireless data loggers have been approved for use
We cannot sell these products to distributors or consumers in countries other than where the wireless units have been approved for use. If these wireless products are used outside of the designated areas of Europe and Australia / New Zealand, T&D Corporation shall in no manner whatsoever take responsibility for the usage of these products, nor be liable in any manner for legal consequences stemming from the usage of these wireless products in unapproved areas.

Wireless Data Communication Function
From the Base Unit connected to your computer you can easily collect temperature and humidity measurements and recorded data from the Remote Units via short wave radio waves. Communication can take place within up to 400 meters if unobstructed and clear.
Note: If the area is not clear and unobstructed, it is possible to use a Repeater to extend the distance. But, only one Repeater can be used between a Base Unit and a set of Remote Units.

Up to 126 units in 1 Group / Up to 32 Groups
Software Set RTR-70 allows you to create and manage up to 32 communication groups assigned to 1 Base Unit and in each group you can register and communicate with up to 126 Remote Units.

3-month Lithium Battery Life /Data Backup Function
A Remote Unit can run for about 3 months consecutively on 1 lithium battery. When battery power becomes low, a warning is displayed and data is automatically saved. For prolonged use we suggest using the optional AC adaptor (AD-0604).
Note: Battery life will depend on the recording environment, recording interval, communication frequency, and ambient temperature. The above battery life test was carried out using brand new batteries and in no way do we guarantee a battery"s life.

2 Measurement and Recording Channels
RTR-71 can measure and record temperature on 2 separate channels, RTR-72 has 1 channel for measuring and recording temperature and 1 channel for humidity. You can select a recording interval from 8 choices, ranging from 1minute to 1 hour.

Warning Monitoring Function for Temperature / Humidity
Our software allows you to set upper and lower limits for each channel (Temp / Temp or Temp / Humidity) and set the monitoring function to periodically check each channel. If a limit has been exceeded a warning will be displayed on your computer screen. Settings can be made differently for each Remote Unit. Perfect for use in tracking and documenting for HACCP.

Current Reading Monitoring
This function makes it easy and effortless to monitor from your computer current temperature and humidity data readings from any number of remote units at your choice of time interval.

1 Unit, 3 Roles
Any unit (RTR-71 / 72) can be made into a Remote, a Repeater or a Base Unit by way of setting it up with the software Set RTR-70.
Note: Units that have been set up as Base or Repeater Units can not measure, display or record temperature or humidity.
