SCC-4275 Coal Spontaneous Combustion Tester (Automatic Type)
Spontaneous combustion of coal is one of the major safety hazards in mines, and the identification of coal spontaneous combustion tendency is the core link of fire prevention. The SCC-4275 coal spontaneous combustion tester (automatic type) launched by East-West Analysis is the designated instrument of "GB/T 20104-2006 Coal Spontaneous Combustion Tendency Chromatography Oxygen Absorption Identification Method". Its production technical conditions and composition structure implement "MT/T 708-1997 Coal Spontaneous Combustion Tester Technical Conditions". With the technical advantages of full automation and high precision, it provides a scientific basis for coal mine safety and helps to upgrade the intelligent management of mine fire prevention and extinguishing.
Core technology: double gas path flow chromatography oxygen absorption
Principle and value
Based on Langmuir's monolayer adsorption theory, SCC-4275 uses dual gas path flow chromatography to determine the physical adsorption of oxygen on coal at low temperature and atmospheric pressure. The degree of spontaneous combustion tendency of coal (Class I: prone to spontaneous combustion; Class II: spontaneous combustion; Class III: not prone to spontaneous combustion) is accurately determined by oxygen absorption, which provides key data support for coal mine design ventilation system and formulation of fire prevention and extinguishing plan.
application scenario
Geological exploration: provide coal seam spontaneous combustion tendency identification report, guide mine design.
Production supervision: monitoring the oxidation characteristics of coal seams in extended mining areas and warning of spontaneous combustion risks.
Scientific research and inspection: universities, mine safety laboratories and metrology departments for coal quality research and standardized testing
Instrument highlights: fully automatic, high-precision, intelligent
Automated operation increases efficiency by 90%
One-button start and stop: using one-button on and off to make operation easier

Voice reminder function: automatic prompt when emptying coal samples to avoid operation errors
East-West Analysis: A Leader in Coal Mine Safety Instruments
As a designated production enterprise of the former Ministry of Coal, East-West Analysis has been deeply cultivating coal mine safety instruments for nearly 30 years. SCC-4275 is an upgraded automatic model of its SCC-4175 measuring instrument, with more mature technology and more convenient operation. The instrument has passed the safety mark certification of mining products and is widely used in national mine safety laboratories, universities and large coal mining enterprises. Choosing SCC-4275 is not only a choice of an instrument, but also a choice of all-round commitment to mine safety.
