TR-73U has a total of three channels: one temperature, one humidity, and one barometric pressure channel. This compact, lightweight model has been designed with low energy consumption for longer battery life; coupled with its easy-to-use software and USB connection makes this product the foundation of our Thermo Recorder line.

The product is an all-in-one package that includes the data logger unit, sensor and software. Simply by connecting to a PC via a USB connection and carrying out a few easy steps, the measurement and recording of data can be started.

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.

Logging Capacity: 8,000 Data Sets

One data set consists of readings for all channels in that type of unit: Temperature, Humidity, and Barometric Pressure.
At the longest recording interval of 60 minutes, recording can continue consecutively for one year.

Accurate, Compact, Lightweight and Affordable

Our exclusive design and technology has allowed us to create a highly accurate yet compact and lightweight unit (55x78x18mm 62g) 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 batteries 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 11 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. Recording Mark
The recording condition will appear.
ON:Recording in progress.
BLINKING:Waiting for programmed start.
2. Data Capacity Scale
After every 2000 readings the scale will be marked from left to right.
3. COM Mark
This will appear when data is being sent or received.
ON:USB cable is connected.
BLINKING:In communication with computer.
4. 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.
5. 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.
6. Unit of Measurement
The unit of measurement for the display will appear.
7. Measurements and Messages Area
Current measurements or operational messages such as FULL or SLP will appear.
