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.

Specifications:

• Features:
  • TR-71U :
  • 2 Temperature Channels
  • 8,000 Readings Each
  • -60 to 155 ° C
  • TR-72U
  • 1 Humidity and 1 Temp. Channel
  • 8,000 Readings Each
  • 0-50 ° C/ 10-95% RH
  • 2 Measurement and Recording Channels in Each Unit.
  • TR-73U : Barometric Pressure 750 to 1100 hPa +/- 1.5 hPa 0.1hPa resolution.
  • The TR-71U gives you two temperature measuring channels and the TR-72S gives you one channel for temperature and one for humidity. 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.
  • TR-71U has one internal sensor for temperature and / or can outfitted with one or two external temperature sensors giving you the flexibility you need.
  • TR-72U comes equipped with an external two channel temperature and humidity sensor which can be removed to allow you to make use of the internal temperature sensor and connect an optional external temperature sensor of your choice.
  • Wide Range of Temperature Measurement: -60 °C to 155 °C
  • The external sensor that comes with the TR-71U can measure and record from -40 °C to 110°C, while optional sensors can give you a range of -60 °C to 155 °C. There is an array of optional external sensors to meet your every need.
  • Humidity Measurement Range: 10-95% RH
  • The two channel external sensor that comes with the TR-72U can measure and record temperature from 0-50degC and humidity from 10-95% RH.
  • 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.
  • 15 Recording Intervals / 2 Recording Methods
  • You can select from 15 recording intervals from one second to one hour.
  • There are also two methods of recording to chose from.
  • One time method:
  • Recording stops when 8,000 readings have been recorded.
  • Endless method :
  • When 8,000 readings have been recorded the oldest data is overwritten and recording continues.
  • 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.
  • Ready to Use - All in One Package
  • Everything you need to get started (main unit, sensor, batteries, software, communication cable and user's guide) is included in this All in One Package. All you need to do is 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
  • We have eliminated the worry of losing data due to power loss or the switch being accidentally turned off.
  • 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.
  • 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
  • Using our specially designed low energy consumption circuit this unit can run on one 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.
  • 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.
  • Software
  • Easy to use Windows comaptible software allows you to control all aspects of set up for any TR-71S/TR-72S unit, as well as to print, and to create text files, tables, and colorful graphs from the recorded data.

• 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.
