High Quality Electrochemical Gas Sensor

Sensor technology is the basis of all Senko products. We are constantly investing in R&D to develop our own products that can not be imitated by developing our own technology.

Now, it is not competitive to make a product with the developed sensor. We will develop new products that will win in the market by developing everything from sensor to product according to the requirements of the market.
