The temperature measurement range of Yadongxing DW-3 (65.85.120) thermometer is 65 ℃, 85 ℃, 120 ℃, and the starting temperature is 65 ℃. The temperature measurement test is a new type of temperature measurement technology in the temperature measurement industry. It adopts the temperature-sensitive color-changing temperature measurement technology. If the temperature measurement paper is pasted on the device, the color will change as the temperature of the device changes. Clearly and intuitively grasp the temperature changes of the equipment. Yadongxing thermometer is a kind of irreversible temperature measuring paper with self-adhesive straps. It has some advantages that temperature measuring instruments do not have, and it is gradually widely used in industry.

| model | temperature range | Number of temperature grids | Sheets per sheet | Size of each piece |
| DW-3(65.75.85) | 65 °C, 75 °C, 85 °C | 3 grids | 120 tablets | 12x30mm |
| DW-3 (65.85.120) | 65 °C, 85 °C, 120 °C | 3 grids | 120 tablets | 12x30mm |
Yadongxing DW-3 (65.85.120) thermometer is suitable for temperature measurement of transistors, integrated circuits, chemical reaction tanks, engine bearings, conductive busbars, switches, joints, transformers and other components, in the power industry, railway industry, processing industry , Manufacturing industry and so on are widely used.
