Message from the Company
In 1983, we ventured into business at the dawn of CCD cameras, which has now become standard technology in the industry. We have been consciously pursuing ways to put the eyes of robots into practical use for severe environments, with the production and development of CCD cameras and related applications. We are proud of our entire product line, especially of Furnacescope® (patent No. 2891672). With its patented cooling jacket structure, this is our registered trademark. It is one of the revolutionary products in the world of heat-resistant security cameras for various furnaces. The development of this camera technology was pioneed in Japan, and we have perfected its structure and function over 30 years of experience. We are glad to say that we have received a great deal of inquities from, and continue to be of great interest to, the top companies in many industrial sectors.
The structure of the heat-resistant jacket contains many great features, including:
(1) The camera itself can enter into a furnace inside and observe for continuous 24 hours.
(2) The pictures are extremely clear.
(3) It is possible to operate under exposure to dusty and high temperature conditions with specified utility supply.

We have expanded the capabilities of the technology and broadened prospective use of it to waste incinerators, distance and height meters, displacement gauges, and more. These capabilities, along with our well-earned reliability, have put us at the forefront of the market.
