TR-73U USB Temperature RH & Baro Pressure Data Logger
The T&D model 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.
*Measuring the degree of air tightness in packaging
*Setting barometric pressure for use with industrial and medical equipment
*Measuring barometric pressure in high-rise buildings (elevators)
*For growth management in mushroom cultivation
At the longest recording interval of 60 minutes, recording can continue consecutively for one year.
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.
