Used to measure the bimetallic thermometer in the pits

General trapezoid shaped pits, in the small, such as a inverted bucket. Each pits have seven or eight square meters in size. Some old cellar pool, pool wall will be attached to a rare like gold layer of pit mud. Pit mud color dark gray, argillaceous soft brittle, fluorescent color, ester full-bodied sweet smell. Pits have built the topography, soil, and the trace elements in the soil, the congenital conditions necessary, also good pit mud, purchased or developed for microbes in pit mud and various strains of infiltration capacity, the walls of the pit is immersed, and accumulate form the hotbed of fermentation. Thus, pits, though small, was fermented riches. Every day, the teacher put a long bamboo pole of fermentation, a hollowed out, to the end of the hollow clip into a thermometer, the bamboo pole into deep pits, in order to measure temperature, in order to judge the cellar pool is fermented grain crops. Every measurement data of a day, and carefully recorded. They use pits thermometer, bimetallic thermometer. This is a kind of measuring instrument in the field of low temperature detection, can be directly measured in the process of various production - 80℃- Liquid + 500 ℃ range steam and gas medium temperature. Widely used in various fields such as food. Instrument at the scene of the bimetallic thermometer display temperature, intuitive and convenient; Safe and reliable, long life, fast reading. Type axial and radial type, universal type, variety complete, adapt to the needs of the various site installation, is the first choice of cellar pool temperature measurement.
