Cautions about using the Sensors

Distributed by MicroDAQ.com, Ltd. www.MicroDAQ.com [phone]

■ Cautions about using the temperature/humidity sensor TR-3100

The sensor can measure temperature within the range of 0 to 50℃ and
humidity within the range of 10 to 95%RH.
Only use the sensor within these ranges.

If extremely severe temperature changes occur, the humidity measurements
may appear abnormal.
Once the sensor's temperature becomes stable, the measurements will return
to normal.

This sensor is not waterproof. Do not get wet.

When measuring with the temperature/humidity sensor in an environment of 0
to 50℃ and less than 30%RH, the measurements may sometimes fluctuate.
This is not abnormal.

dusty places) it may be necessary to change th

- When the temperature/humidity sensor is not being used, please place it in
the attached vinyl bag with the drying agent included and store it in a cool
dark place with a temperature of between 5 to 25℃ and a humidity of below
30%RH.

- Attached to the temperature/humidity sensor are two stickers: a wetness
detection sticker and a temperature detection sticker. If either of the stickers

About Thermo Recorder TR-73U

Distributed by MicroDAQ.com, Ltd. www.MicroDAQ.com [phone]

■ Outline

TR-73U Thermo Recorder is a data logger capable of measuring,
displaying and recording temperature, humidity, and barometric
pressure data. TR-73U h a s a t o t a l of three channels: o n e
temperature, one humidity, and one barometric pressure channel.
The data recorded into the TR-73U 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

-Barometric Pressure Measuring Range：750 〜 1100hPa

The TR-73U with the internal barometric pressure sensor can measure and record in a
range of 750 to 1100 hPa.

-Temperature Measuring Range：-40 〜 110℃

The TR-73U with the sensor included in this package can measure and record in a range
of 0 to 50℃ , but by purchasing one of our optional sensors it is possible to measure and
record in the wider range of -40 to 110℃ .
Please take a look at our full range of optional sensors to find one to match your
application.

-Humidity Measuring Range：10 〜 95%RH

The TR-73U 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.

-Amount of Recorded Data：8000 readings x 3 channels

One channel can record and hold up to 8000 measurement readings.
At the longest recording interval of 60 minutes, recording can continue consecutively for
1 year.

-10 Months of Operation with just 1 AA Alkaline Battery

Our low energy consumption design gives you ten months 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 warehouse.
