YS3033
Low-Barometric Pressure Discharge Tube
For demonstrating electric discharging under the low barometric
pressure, The discharge varies with different barometric pressure
in the tube.

Outer diameter: 25\1mm |
|
YS3034
Low Atmospheric Pressure Discharge Tube Set
It's used for demonstrating the phenomenon of discharge under
low atmospheric pressure. The discharge is varied due to the
different atmospheric pressure in discharge tube.
