Mk II Inner Measuring Cylinder – Crystal Rain Gauge

Mk II Inner Measuring Cylinder

Our product is a glass rain gauge that won’t discolour or fade like the rest of them. We have used borosilicate (very tough) glass and marine-grade stainless steel to create the most durable and reliable  rain gauge.


Crystal Rain Gauge™ can measure up to 200mm of rainfall without emptying. Its large, annealed graduations are easy to read and will never fade.




The Crystal Rain Gauge stainless steel mounting bracket should be fixed to a secure support using the four stainless steel screws supplied. A fence post or similar is ideal. Make sure the bracket is vertical so the collection opening is level. 
With the bracket mounted, slide in the outer glass cylinder and rotate it so the measurements are visible through the left window.
Assemble the collection funnel and inner cylinder as follows:
1. Check the silicone o-ring is in the groove around the collection funnel and the segmented foam rubber gasket is in place in the funnel spout.
2. Carefully insert the lugs on the inner cylinder in the slots on the funnel, push against the foam gasket and rotate anti-clockwise to secure them. The inner cylinder will now hang from the funnel with the gasket securing it.
3. Carefully lower the funnel and inner cylinder assembly into the outer cylinder and align its graduations so they’re visible from the front of the rain gauge.

Shipping costs will vary depending on your location within Australia. 

Due to the glass, we've had to take extra packaging precautions to minimise breakages.
