The TR-71Ui may look like a toy but it isn’tthis handy Thermo Recorder measures and records temperature and humidity. The recorded data can then be downloaded to a computer via Tecpel exclusive software where colorful graphs and tables can be easily created. By making use of two alkaline batteries this low energy using a compact lightweight unit can be left alone to record continuously over long periods of time. And with their exclusive circuitry, Tecpel has created a model that brings the customer accuracy of more expensive models at a price that is affordable.

TR-71U from Tecpel comes with the following features:

• 2 Temperature Channels.
• The present measurements for both channels are also displayed alternately on the main unit making it easy to know the current temperature and humidity in a flash.
• 8,000 readings.
• -60 to 155 ° C.
• TR-71U has one internal sensor for temperature and /or can be outfitted with one or two external temperature sensors giving you the flexibility you need.
• The external sensor that comes with the TR-71U can measure and record from -40 °C to 110°C, while optional sensors can give a range of -60 °C to 155 °C.
• Large Data Capacity: 8,000 Readings X 2 Channels.
• Each Channel can record up to 8,000 readings; giving about one year of continuous recording at a recording interval of 60 minutes.
• 15 Recording Intervals / 2 Recording Methods.
• Users can select from 15 recording intervals from one second to one hour.
• There are also two methods of recording to choose from.

• 1.       One time method:

• Recording stops when 8,000 readings have been recorded.
  
  2.       Endless method :

• When 8,000 readings have been recorded the oldest data is overwritten and recording continues.

• Accurate, Compact, Lightweight and Affordable
• Tecpel’s exclusive design and technology has allowed them to create a highly accurate yet compact and lightweight unit (55x88x24mm 95g) that is unbelievably affordable.
• Ready to Use - All in One Package
• Everything user needs to get started (main unit, sensor, batteries, software, communication cable, and user’s guide) included in One Package. The only requirement is to supply the computer.
• 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.
• Reliable Backup Function
• Tecpel has eliminated the uncertainty of losing data due to power loss or the switch being accidentally turned off.

1.       A.      When Battery Power becomes Low:

• When battery power becomes low a battery life warning will appear on the unit's display indicating that the battery should be changed. If within a short time the battery is changed, measurement and recording will not be interrupted and there will be no data loss. If the battery is not changed the unit will automatically go into SLEEP mode whereby measurement and recording will stop but, due to our BACK UP FUNCTION, data will not be lost and will remain saved for one year.

1.       B.      When the switch is turned OFF:

• If while recording the power switch is accidentally turned OFF, data will not be lost but will be saved for one year from the time it was switched OFF. Note: Even if the unit is in sleep mode it needs battery power. Hence, a total loss of battery power or removal of the batteries will result in the loss of data.

• One Year Continual Use on One Set of Batteries
• Specially designed low energy consumption circuit allows this unit to run on one AA Alkaline battery for up to one year of continued use. No need to worry about where the unit is placed as the battery will allow it to measure and record over long periods of time whether the unit is in transit or in a distant place. Note: The 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, the company guarantees a battery's life.
• Software: Easy to use Windows compatible software allows the user to control all aspects of setting up for any TR-71 unit, as well as to print, and to create text files, tables, and colorful graphs from the recorded data.

Functions:

• USB Connection
• Easy-to-use USB computer connection makes things not only simple but allows the user 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
• Tecpel’s exclusive design and technology has allowed them 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. Note: The 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 a 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.
• Channel Mark: The channel number of the measurement being displayed will appear.
• Recording Mark: The recording condition will appear.
• ON: Recording in progress.
• BLINKING: Waiting for the program to start.
• Data Capacity Scale: After every 2000 readings the scale will be marked from left to right.
• COM Mark: This will appear when data is being sent or received.
• ON: USB cable is connected.
• BLINKING: In communication with a computer.
• Recording Mode:

                    1)      ONETIME: When the number of recorded readings reaches 8000, “FULL” will appear in the unit's LCD display and recording will automatically stop.

                    2)      ENDLESS: When the number of recorded readings reaches 8000, the oldest data reading will be overwritten and recording will continue.

• Battery Life Warning Signal: When the battery power becomes low, this will appear on 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.
• Unit of Measurement: The unit of measurement for the display will appear.
• 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.
