Product Description

Features:

• DT-NH831D is a new product based on the latest optoelectronics technology. It uses high-performance second-generation/third generation image intensifier. It has the characteristics of excellent performance, small size, light weight, clear image, simple operation, high performance-price ratio, and the magnification can be changed by replacing objective lens (or connecting multiplier lens). 
• The fuselage is made of all metal. It is small in size, lightest in weight and high in strength.
• Good optical quality, clear imaging, high brightness, uniform brightness throughout the observation range.
• Skillful design and high-quality image tube are adopted to maximize the cost-performance ratio of products.
• The product has strong practicability and can be applied to military observation, coastal defense reconnaissance, public security surveillance, forensics, customs anti-smuggling, etc. 
• Waterproof IP65 or IP67
