USB Connection
Our easy-to-use USB computer connection makes things not only simple, but allows you to connect several units at the same time.
Simultaneous Monitoring of Multiple Channels of Data
With the attached software it is possible to view current measurements and current trends in a changing graph form. Graphs can be opened for the same number of units as are connected and can be simultaneously viewed.
Large Data Capacity: 8,000 Readings x2 Channels (TR-73U:8,000 x3 Channels)
Each unit is equipped with a large data capacity of 8000 readings x 2 channels for TR-71U/72U and 8000 readings x 3 channels for TR-73U.
Accurate, Compact, Lightweight and Affordable
Our exclusive design and technology has allowed us to create a highly accurate yet compact and lightweight unit (55x88x24mm 95g) that is unbelievably affordable.
One Year Continual Use on One Set of Battery
Using our specially designed low energy consumption circuit this unit can run on two AA alkaline battery for up to one year of continued use. No need to worry about where you place it as the battery will allow you to measure and record over long periods of time whether the unit is in transit or in a distant place.
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.
Adjustment Function
By setting adjustment values beforehand, you can record and display the post-adjusted measurement values.
High Speed Data Transfer
Possible to transmit one unit of full data (8,000 readings) to computer in about 8 seconds.
Easy to Read Multi-Functional Display.
The easy to read large sized LCD displays present readings, recording condition, battery life warning, amount of data readings, and unit of measurement among other things.

1. Channnel Mark
The channel number of the measurement being displayed will appear.
2. Recording Mark
The recording condition will appear.
ON:Recording in progress.
BLINKING:Waiting for programmed start.
3.Data Capacity Scale
After every 2000 readings the scale will be marked from left to right.
4.COM Mark
This will appear when data is being sent or received.
ON:USB cable is connected.
BLINKING:In communication with computer.
5.Recording Mode
ONETIME: When the number of recorded readings reaches 8000, "FULL" will appear in the unit's LCD display and recording will automatically stop.
ENDOLESS: When the number of recorded readings reaches 8000, the oldest data reading will be overwritten and recording will continue.
6.Battery Life Warning Signal
When the battery power becomes low, this will appear in the LCD display. If the battery power becomes even lower, SLP will appear and normal operations will stop. If the signal appears, please change the battery as soon as possible.
7. Unit of Measurement
The unit of measurement for the display will appear.
8. Measurements and Messages Area
Current measurements or operational messages such as FULL or SLP will appear.
