Frequently Asked Questions for the T&D TR-72NW-S Wired LAN Temperature & Humidity Data Logger:

1. What is the TR-72NW-S and what is it used for?

The TR-72NW-S is a 2-channel temperature and humidity data logger from T&D Corporation featuring a wired LAN interface for automatic data upload.

It’s designed to monitor environmental conditions in storage areas, laboratories, pharmaceutical warehouses, food facilities, and other critical spaces.

2. What are the measurement ranges and accuracies?
Temperature: –25 °C to +70 °C, resolution 0.1 °C, accuracy ±0.3 °C.
Humidity: 0 %RH to 99 %RH, resolution 0.1 %RH, accuracy ±2.5 %RH (20–80 %RH).
3. What power supply does it require?

The unit draws power from an external AC adapter (AD-05A2 or AD-05C2), accepting 100–240 VAC and outputting 5 VDC.

It does not contain an internal battery, so continuous AC connection is required for logging.

4. How does network connectivity work?

The TR-72NW-S has an Ethernet (RJ-45) port supporting DHCP or static IP.

You configure network settings via the front-panel buttons and LCD, then plug a standard LAN cable into your switch or router for automatic data uploads.

5. What’s the onboard memory capacity?

It stores up to 1,000,000 readings (temperature and humidity pairs).

When the memory is full, it overwrites the oldest data in a first-in, first-out manner.

6. Can I adjust the logging interval?

Yes. You can set the recording interval anywhere between 10 seconds and 24 hours to suit detailed or long-term monitoring needs.

7. How do I retrieve the recorded data?
Automatic: Data is pushed to the free T&D WebStorage Service or to your local PC running T&D Data Server.
Manual: Connect via USB Mini-B to a computer with the “TR7 for Windows” software to download CSV files and generate reports.
8. Which software and apps are available?
TR7 for Windows: configure settings, download data, export graphs.
T&D Graph: visualize data and print reports on PC.
T&D Thermo (iOS/Android): view real-time graphs and alerts on smartphones.
T&D Data Server: local server software for data reception and storage.
9. How are alarm notifications handled?

When temperature or humidity exceeds set limits, the TR-72NW-S will:
Send email or SMS alerts via WebStorage Service or Data Server.
Display a warning icon on the LCD.
Log the alarm event with a timestamp.
10. How do I set alarm thresholds?

Use the ▲/▼ buttons and the Set key to enter the “Alarm Set” menu.

Select the channel, input high/low threshold values, then save and exit.

11. What maintenance and calibration are recommended?
Clean the sensor with compressed air or a soft cloth every six months.
Have the temperature and humidity sensors calibrated by a certified lab every 1–2 years.
12. How can I upgrade the firmware?

Connect the logger to a PC via USB, launch TR7 for Windows, and load the firmware file provided by T&D.

13. What are the installation and mounting options?

You can mount it on a wall using the TR-07K2 bracket or place it on a flat surface.

For wall mounting, drill two holes 60 mm apart, hang the bracket, then secure the logger in place.

14. Can I replace or extend the external humidity sensor?

Yes. Compatible extension cables include TR-1C30 (3 m) and TR-5C10 (10 m).

Ensure you use T&D sensors such as THA-3001 or THA-3151 for full compatibility.

15. What common issues might I encounter and how do I troubleshoot?
No LAN connection: check DHCP/static IP settings, network cable, and link LED.
Data not uploading: verify WebStorage Service account or Data Server status, then review the error log.
LCD unreadable: perform a factory reset by pressing the Reset button.
16. What optional accessories are available?
TR-07K2: wall-mount bracket
AD-05A2/AD-05C2: AC adapters (Type A/C plugs)
TR-1C30/TR-5C10: sensor extension cables
SHA-3151: high-precision temp/humidity sensor
US-15C: USB Mini-B cable
