TR-71U  2-Channel Temperature recorder

    TR-71U 2-Channel Temperature recorder

    Manufacturer: TandD Corporation


    This product is superseded by the TR-71Ui.

     

    TR-71U/TR-72U Thermo Recorders are data loggers capable of measuring, displaying and recording temperature and humidity data.

    TR-71U has two temperature channels and TR-72U has one temperature and one humidity channel. TR-73U has a total of three channels: one temperature, one humidity, and one barometric pressure channel.

    These compact, lightweight models are designed for low energy consumption for longer battery life; coupled with its easy-to-use software and USB connection makes this series 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 computer and carrying out a few easy steps, the measurement and recording of data can be started.

    TandD's TR-71U/72U/73U and TR-51S/52S have been tested for electro-magnetic radiation and confirmed to comply with the requirement of RTCA DO-160E, Section 21: Emission of Radio Frequency Energy.

    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

    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.

    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.

    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.
