Vaposkop VK 16
Extremely clear and simple visual function test
If the steam trap is functioning perfectly, the tip of the Vaposkop's deflector is immersed slightly in the water seal, which is produced in the sightglass due to the siphon effect. If a loss of steam occurs, the amount of water in the seal decreases and the tip of the deflector is no longer immersed. If condensate is banking up, the sightglass is filled completely.
