TR-73U T&D Thermo / Barometric Pressure Recorder Product ID: TR-73U

TR-73U
For Measuring and Recording Temperature and Humidity

These handy Thermo Recorders measure and record temperature and humidity. The recorded data is then downloaded to your computer via our exclusive software whereby colorful graphs and tables can be easily created. By making use of two alkaline batteries this low energy using compact lightweight unit can be left alone to record continuously over long periods of time. And with our exclusive circuitry we have created a model that brings you the accuracy of more expensive models at a price you can afford.

  • Functions
    • USB Connection One Year Continual Use on One Set of Batteries
    • Simultaneous Monitoring of Multiple Channels of Data High Speed Data Transfer
    • Large Data Capacity: 8,000 Readings X 2 Channels Adjustment Function
    • Accurate, Compact, Lightweight and Affordable Easy to Read Multi-Functional
  • More Functions:
    • 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 X 2 Channels
    • Each channel can record up to 8,000 readings; giving you about one year of continuous recording at a recording interval of 60 minutes.
    • 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 Batteries
    • Using our specially designed low energy consumption circuit this unit can run on two AAA 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.
    • 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.
    • 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.
  • Application Examples :
    • Performance testing of humidity and heat control in housing Temperature and humidity management for greenhouses
    • Temperature management in temperature controlled warehouses
    • Humidity and temperature management in mushroom cultivation
    • Recording temperature and humidity in subways and train cars
  • Q & A:
    • 1. Customer wanna know sampling rate of instruemnt in measurement mode and recording mode.
    • ANS:
    • 1. TR-72U's sampling rate
    • a) In Measurement Mode :
    • When recording interval is 1 sec, 1 sec.
    • When recording interval is 2 sec. or more, 2 sec.
    • b) In Recording Mode :
    • Same as the recording interval you set. (Specifically, TR-72U record the
    • measured value right before the recording time.)
    • 2. Regarding excel format customer wanna know if it's possible to get data
    • directly in Excell format
    • without sw, just with USB drivers.
    • ANS:
    • 2. It seems that you can do that with the TR-72U's DLL, but we do not
    • know the exact mothod because this is not a matter of our products.
