XFGsertXD Handheld Brix Sugar Content Refractometer ATC Concentration Test | Measures liquid concentration, sugar or alcohol content for food, beverage, brewing and laboratory testing

The lamp is made of special sodium-resistant glass blown into a tube, the tube contains metal sodium, and the outside is sealed with a glass shell. After ignition, it can emit strong 589.0 nm and 589.6 nm sodium lines. It has good monochromaticity. It is often used as a monochromatic light source in polarimeters, refractometers, polarimeters, and other instruments. 1.
