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. The data recorded into the TR-71U

TR-72U
units can then be downloaded quickly via USB cable to your computer
whereby with our exclusive software you can easily process the data into
graphs, tables, save to files and/or print it out. Moreover, it is possible to
connect more than one unit at the same time.

Basic Functions
●
Temperature Measuring Range :
-
60 to 155
℃（
TR-71U
)
The TR-71U with the sensor included in this package can measure and
record in a range of
-
40 to 110
℃
, but by purchasing one of our optional
sensors it is possible to measure and record in the wider range of
-
60 to
155
℃
. Please take a look at our full range of optional sensors to find one to
match your application.
●
Humidity Measuring Range : 10 to 95
％
RH
（
TR-72U
)
The TR-72U with the sensor included in this package can simultaneously
measure and record temperature in a range of 0 to 50
℃
and humidity in a
range of 10 to 95
％
RH.
●
Data Recording Capacity : 8000 readings
×
2 channels
One channel can record and hold up to 8000 measurement readings. If set
at a recording interval of 1 hour, a unit can continuously record for about
one year.
●
1 Year of Operation with just 1 AA Alkaline Battery
Our low energy consumption design gives you one year of continuous
operation with only one AA alkaline battery. This gives you the freedom to
use the data loggers in places where they can be left alone for long periods
of time, such as, in transportation or refrigeration.
Note:
Battery life varies depending upon the type of battery, the measuring
environment, the frequency of communication, and the ambient temperature
in which it is used. Specifications and explanations used in this User's
Manual are based on operations carried out with a new battery and are in
no way a guarantee of your actual battery life.

Battery Life Warning Display
When the battery power becomes low, a battery life warning signal will
appear in the unit’s LCD display. If the battery power becomes even lower
the unit will automatically go into sleep mode in order to protect the data.
●
15 Recording Intervals
Select from 15 Recording Intervals
(
from 1 second to 1 hour
)
to meet your
needs. Select from 2 Recording Modes
One-time Mode : When the number of recorded readings reaches 8000,
"
FULL" will appear in the unit’s LCD display and recording
will automatically stop.
Endless Mode : When the number of recorded readings reaches 8000, the
oldest data reading will be overwritten and recording will
continue.
●
Backup Function
When battery power becomes low, a battery life warning signal will appear
in the unit’s LCD display and if the battery power becomes even lower the
unit will automatically go into sleep mode in order to protect the data. In
sleep mode all normal operations will stop and it will become impossible to
switch on the power of the main unit.
Note:
If the main unit remains in sleep mode for about 1 month without a
change of battery, or if the battery is left out of the unit for more than 2
minutes, all recorded data will be lost.
●
Current Readings Monitoring Display
With our exclusive software, you cannot only monitor the current
measurements at a set interval, but can view those measurements in a
continually changing graph. You can simultaneously display the current
measurements and corresponding graphs for the number of units you have
connected.
●
Adjustment Function
Bt setting adjustment values beforehand, you can record and display the
post
-
adjusted measurement values. You can choose from two adjustment
methods: 1-point and 2
-
point. Adjustment will be carried out using an
adjustment equation of Y
＝
aX
＋
b ; where X is the pre-adjusted measurement
value and Y is the post-adjusted value.
