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.
