红外探测器尺寸(像素表示)
 The detector size indicates the number of temperature measurement points (pixels) with which the thermal imager is equipped. The more pixels, the more detailed and clearer the measuremente objects are presented. |
160 x 120 |
320 x 240 |
640 x 480 |
SR红外超像素技术)
SuperResolution technology improves the image quality by one class, i.e. the resolution of the thermal image is four times higher. |

热灵敏度(NETD)
The thermal sensitivity (NETD) displays the smallest temperature difference which can be resolved by the thermal imager. The lower this value is, the smaller the temperature differences which can be measured. |
