DT-NH921
Product description：
DT-NH9 is a new product developed based on the latest optoelectronic technology. The instrument uses a high-performance second-generation/third-generation image intensifier tubes. There are 3 versions: night vision version, video output version, thermal fusion.The version has excellent performance, small size, light weight, all-metal housingl, uniform vision, clear imaging, simple operation, can be equipped with night vision image output, high efficiency, and the night vision can be changed by changing the objective lens (or connecting the A-focal lens). The instrument has built-in infrared auxiliary light source and automatic anti-glare protection system.
