GD-35 type (foreign corresponding model R2868)

GD-35 type photosensitive tube is a glass structure, cold cathode and gas-filled diode. GD-35 is one of the main models of our company. It has long-term inventory, which has obvious price advantages and flexible business methods.

The tube has the characteristics of high sensitivity and fast response, and it can detect 185 to 260 different narrow spectral sensitive sources. It has a small volume and a wide sensitivity angle (directivity), and can quickly and accurately detect the weak ultraviolet rays emitted from the flame. Mainly used in ultraviolet flame detectors, electric spark monitoring and ultraviolet measurement.
