HCW-ⅢA 型红外测温仪是一种远距离小视场新型测温仪。它采用了变焦距红外光学镜头,配有望远镜同轴瞄准,显著地提高了距离系数,其值为400,优于同类进口产品(日本产 TSS-180型为200,美国产 HSA-201型为300)。采用比色测温法,提高了实际使用测量精度。为适应野外操作方便,寻找出小目标最高温度,设置有数字暂停开关及最高温度自动保 HCW-ⅢA-type infrared thermometer is a new long-distance field of view thermometer. It uses a variable focal length infrared optical lens, with coaxial telescope aimed at a significant increase in the distance coefficient, the value of 400, better than similar imported products (Japan’s TSS-180 type 200, the United States HSA-201-type 300). The use of colorimetric temperature measurement method to improve the actual use of measurement accuracy. In order to adapt to the field operation convenience, find out the maximum temperature of the small target, set the digital pause switch and automatic maximum temperature
