Newly developed for use with the well-known thin spectral tubes, making the use of these both easier and significantly more secure. The spectral pipes are mounted in insulated holders, provided with a contact electrode. The lower holder is spring-loaded and can be displaced up and down, ensuring easy mounting of the spectral tube.
Spectral tubes with a length of between 224 and 299 mm and a diameter of max. 15.5 mm can be used.
The holder's built-in power supply delivers a voltage of up to 6 kV.
The operating voltage is significantly lower and controlled by the variable current limiter. The current can be adjusted between 2 and 8 mA using a button on the back.
Connect to mains.
This spectral tube holder is a replacement for model 285550.
