Heller's Ring test is used to clinically detect the presence of albumin in urine.
The presence of albumin is indicated by the formation of white ring at the junction of the solution and concentrated nitric acid
Heller's test, also known as the finger drop test, is used to assess grip strength. It can help in identifying weakness or paralysis in the hand and forearm muscles, often indicating nerve damage or other neurological conditions.

The brown ring test is a qualitative test used to detect the presence of the nitrate anion. In the test, a sample containing nitrate ions is treated with freshly prepared iron(II) sulfate solution and concentrated sulfuric acid. A brown ring at the junction of the two layers forms if nitrate ions are present.
The Brown ring test is performed by adding a small amount of nitric acid to a nitrate solution containing a Fe2+ ion. A brown ring forms at the junction of the two layers if the nitrate ion is present. The test is based on the reaction between Fe2+ and NO+ ions.

A test ring in a heat exchanger is a device used during the manufacturing process to verify the integrity and quality of the welds. It typically consists of a metal ring that is welded onto the heat exchanger assembly and then tested for leaks or other defects using pressure or other testing methods. This helps ensure that the heat exchanger will perform effectively and safely once it is installed in its intended application.
