Yadongxing DW-4 (55.65.75.85) temperature measuring paper is a 4-compartment temperature measuring patch with four temperature points of 55°C, 65°C, 75°C, and 85°C. Yadongxing DW-4 temperature measuring paper is a large sheet with 90 small pieces on it. When using it, the user can take off a small piece with scissors or tear it by hand and stick it on the temperature measuring part. Yadongxing temperature measuring paper is a new temperature measuring technology, which is different from thermometers and temperature measuring wax sheets. It is an irreversible temperature measuring paper with temperature recording function, over-temperature discoloration and protective film on the surface, which makes up for other temperature measuring papers. Inconvenient to carry the tool or inconvenient to paste, etc. At the same time, it reports the temperature of the temperature measuring equipment in a simple and rude way, and it is clear before and after discoloration.

| model | temperature range | Number of temperature grids | Sheets per sheet | Size of each piece |
| DW-4 (55.65.75.85) | 55 °C, 65 °C, 75 °C , 85 °C | 4 cells | 90 tablets | 12x40mm |
1. Choose a clean and dry temperature measurement part, or clean the temperature measurement part to remove oil or dust.
2. willCarefully tear off the Yadongxing DW-4 (55.65.75.85) temperature measuring paper. Be careful not to touch the sticker on the back of the temperature measuring paper with your hands, so as not to affect the adhesive force of the sticker.
3. When pasting the temperature measuring paper, press firmly on the equipment, try to pinch the four corners of the temperature measuring paper tightly, remove the tiny air gap between the glued surfaces, and ensure that the glued surface is under pressure to play the role of bonding , the bond is stronger.
4. After the DW-4 (55.65.75.85) temperature measuring paper is bonded to the device, the color will change with the temperature of the device, and the user can detect the change of the temperature measuring paper during this process.
5. After the temperature measurement is completed, just tear off the temperature measurement paper.
