Within 20 years «Spectroflash» developsand produces serially portable x-ray units,
intended for the control of various metal
structures under field conditions.
These devices can be divided into two
independent classes.

The first class includes devices based on theexplosive electron emission in the X-ray tubewith a cold cathode.
PAMIR-200, PAMIR-300

The advantages of the pulse X-ray apparatus:
- small size and weight- easy operation- the possibility of both directional and
panoramic X-raying

These devices are used in self-propelledX-ray machines (crawlers), the distinctivefeature of which is the use of a low-power
pulse apparatus as the command radiationsource, installed on the controlled pipe and
managed by the operator from a distance that
ensures the complete security

The second class of devices produced by ourcompany consists of X-ray apparatus with
constant voltage across the electrodes of X-raytube with thermoemission cathode.As a source of high voltage high frequency
transformers are used in combination with thecascade voltage multipliers

Unlike pulse apparatus, high-frequencyapparatus of continuous action have
considerably longer service life and the betterradiographic characteristics, but they are moredifficult to operate, and that is most important,
more expensive
