The base is solid stainless steel with an anti-turbulence orifice to keep the liquid steady within the sight glass while there is a rolling boil in the pan it is connected to. The glass is fire polished and shatter-resistant. The scale can be placed by you to ensure the level is perfectly calibrated to your pan.
We offer two different connection styles. The most common is to connect the Sight Glass to a float box. If your float box doesn’t have a drain on the bottom of it, please contact us. We may be able to add a port to it for you to accept our sight glass.
If you don’t have a float box, that’s no problem. Select the “Connect to Draw-Off Port” option. You will still be able to use the same port for drawing off. You will just have the added benefit of being able to see your pan’s sap level.
