1.6. Can TC001 Detect Objects Underwater, Through Glass, or Walls?
No. Infrared detectors mainly detect the long-wave infrared region of 8~14μm and can only be used to measure surface temperature. They cannot observe through water, ordinary glass, or walls.
1.7. Can TC001/TC002 Measure Glass?
Yes. For translucent materials, such as plastic film or glass, ensure the background is uniform and the temperature is lower than the object being measured.
1.8. Why Does the Temperature Reading Increase When the Device is Close to an Object/Why is the Temperature Lower at a Distance and Higher When Close?
Infrared radiation attenuates as it travels through the atmosphere. The longer the distance, the greater the attenuation. Therefore, the accuracy of temperature measurement decreases at long distances. To ensure measurement accuracy, go to Profile-Settings-Temperature Calibration-Point to Distance, and enter the actual distance (maximum 5 meters) to obtain the corrected temperature.

1.38. Topdon TC001 device is not accurate in detecting cold metal temperatures.
If the metal surface is smooth and reflective, the measurement will be inaccurate.
Although the thermal imager measures the surface temperature of objects, it is heavily affected by reflections, such as glass or smooth metal. However, since different smooth surfaces have different emissivity, they may be as low as 0.5.
Therefore, in this case, it is recommended to stick a layer of matte tape or apply a non-reflective coating on the surface of the object to be measured for accurate measurement.
1.39. How to perform image calibration?
You can select “Image Calibration” in the “Me” section of the APP.
1.40. How to distinguish whether the imaging anomaly reported by the customer is due to device issues or improper operation/settings.
① Have the user try another phone or tablet to rule out device issues.
② Connect the device and check if the blue indicator light on the device side is on, and listen for the shutter sound. If the blue light is on and there is a shutter sound, the device is connected. It may be a system incompatibility or permissions not being opened.
③ The simplest way is to have the user reinstall the app and agree to all permission requests (USB connection permission, album permission, app privacy agreement, some phones also need to separately enable OTG permission).
1.41. Can TC001/TC002 detect insects (cockroaches/cicadas, etc.)?
Thermal imaging cameras generate thermal images by detecting the infrared radiation emitted by objects. As long as there is a temperature difference between the object and its surrounding environment, it can be detected.
In practical use, there are three main factors that affect measurement: emissivity + measurement distance + ambient temperature. Measuring insects is not easy, as the control of distance and the influence of ambient temperature are significant.
1.42. Can TC001/TC002 measure temperature on reflective metal surfaces?
Yes, it can measure. Glass and smooth surfaces reflect almost all infrared light, so the temperature is not accurate. We need you to adjust the emissivity before measuring. When measuring shiny objects, you can cover the surface of the object with spray paint, matte black powder, or masking tape. Measure the temperature of the covered or spray-painted surface, which is the true temperature. Operation path: In the APP, go to “My” — “Temperature Correction” — “Emissivity”, and manually input the corresponding emissivity. Emissivity refers to the ability of an object to radiate infrared energy. The radiated energy indicates the temperature of the object. The emissivity value ranges from 0 (a polished mirror) to 1.0 (a black body); the emissivity of most organic materials, paints, or oxidized surfaces is close to 0.95. We provide a common emissivity table. For niche objects, we recommend you consult relevant materials and input the accurate emissivity to ensure measurement accuracy.
1.43. Why can’t TC001 be directly recognized by some phones, but can be recognized when using an extension cable?
Some Type-C interfaces on phones lack a grounding pin. If TC001 is directly connected, it cannot be recognized. However, the extension cable itself has a grounding pin, so it can be recognized after connection. For such phones, it is recommended to use an extension cable for connection.
1.44. What is the maximum detection distance of TC001/TC002?
The maximum detection distance is 50m, and the effective temperature measurement distance is within 5m.
1.45. Why is the temperature measurement of TC001/TC002 not very accurate?
The temperature resolution of TC001/TC002 is ±2%. The temperature range for the normal temperature setting is: -10150℃ (14302°F), and for the high temperature setting is: 150-550℃ (302~1022°F). Please select the corresponding temperature setting in the APP before testing.
1.46. How to save the zoom factor and position settings to make the infrared image (TC001) and visible light image (phone) overlap.
We regret to inform you that the device does not support this feature. Since the APP uses the phone’s camera, their perspectives are quite different, and you can only manually adjust each time. We recommend purchasing TC001 Plus, where the visible light and thermal imaging are directly overlapped.
1.47. How to make the thermal imaging interface of TC001/TC002 not display temperature values?
Click the “Temperature Value” icon in the menu bar at the bottom of the thermal imaging interface, and select “Delete” to remove the temperature value display.
1.48. TC001/TC002 How to disable the pseudo-color bar on the thermal imaging interface?
Click the “Settings” icon in the menu bar at the bottom of the thermal imaging interface, and set the “Pseudo-color bar” status to off to remove the pseudo-color bar display.
1.49. Can thermal imaging pictures taken by TC001/TC001Plus/TS001 on the APP be opened and analyzed on TCView?
Not supported. The APP (Android) and TCView (Windows) are two different systems, and thermal imaging pictures taken by the phone cannot be opened and analyzed on the computer.

3. Troubleshooting
3.1. Why does TC001 not display the thermal imaging screen but only shows -273.1℃ after connecting to the phone?
It is recommended to follow the steps below for troubleshooting:
- Try connecting to another phone to see if it displays normally. If it does, it might be a compatibility issue with the phone. If it doesn’t display, it could be a hardware issue.
- Check if the phone is running other USB software. If so, close it and then try connecting TC001 again. If it still doesn’t display, it might be a compatibility issue.
- Download a third-party thermal imaging software (such as “thermal eye X”) to test. If it still doesn’t display, it might be a compatibility issue.
