The TandD RTR-72 is a Intelligent two channel transmitter / datalogger with local display. Supplied with external temperature and humidity sensor for measurement between 0 to 50°C/10 to 95%RH

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.

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 adapter (AD-0604)

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 minute to 1 hour.

Example of Communication Group Set-up

Office / Building / Factory / Store

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 Relay or a Base Unit by way of setting it up with the software Set TR-70.
Note: Units that have been set up as Base or Relay Units can not measure, display or record temperature or humidity
