I purchased 38x200mm test tubes to replace rain gauge tube that broke & I could not locate any other option local/online that would fit the - apparently - special size for the rain gauge. While I was disappointed the test tubes did not have incremental markings (for rain measurement), since the test tube fit the rain gauge perfectly, I was able to transfer markings from prior/broken tube to the new test tube. Subsequently, able to use the new test tube for my rain gauge.

The test tubes were exactly as described but 3 of the 12 were broken upon arrival. Indigo replaced the broken tubes after I contacted them. Great service!
