The Enclosing-Type Thermometer is a high-precision glass instrument specifically engineered for laboratory and industrial environments where readability and chemical protection are paramount. Unlike standard solid-stem thermometers, where the scale is etched directly onto the outer glass, the “Enclosing Type” features a secondary internal glass tube that houses the scale—typically printed on a high-contrast white opal glass plate. This dual-layer construction protects the temperature markings from aggressive chemical vapors, friction, and environmental wear, ensuring that the instrument remains perfectly legible throughout its entire service life. It is the preferred choice for chemical processing, distillations, and high-standard laboratory research.

Opal Glass Scale (Inclusion Design): The measurement scale is printed on a separate strip of milky-white opal glass and sealed inside the outer protective sleeve, providing a sharp, high-contrast background for the liquid column.
Hermetically Sealed Protection: Because the scale is enclosed, it is physically impossible for the markings to be rubbed off, stained by chemicals, or obscured by surface scratches on the outer glass.
