The base is solid stainless steel with an anti-turbulence oriface 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.
When you attach your Sight Glass to your pan’s draw off port, you will still be able to draw off syrup. You will just have the added benefit of being able to see your pan’s sap level. Alternatively, if you have a Divided Pan, you have the option to attach this Sight Glass to the INLET port of your pan instead. Several configurations can be achieved from this kit (see photos above), making this a very valuable and versatile tool for any Smoky Lake 16″ x 30″ pan (AKA StarCat pan).
NOTE: Always keep your sap level at about 2″ depth to prevent scorching of your syrup and pan. If your Sight Glass indicates that you have 1″ depth, that actually means that you have 1″ OR LOWER, and you should add sap right away.Instruction Sheet
