● Complete ancillary analysis function:Including: coal blending stripping, monitoring coal blending in production, simulation and synthesis of coal blending diagram, automatic temperature correction, multiple report average and other necessary functions in coking production.

Provide the most complete supporting technical services:

● including: supporting light fast preparation technology (several minutes/light), into the plant wet coal integration rapid sample technology, free detailed personnel technical training, coal and rock application guidance, after-sales warranty, etc..

Technical parameters:

● linear calibration: four-standard method. The measured values of the four standard samples in the range of 0-1.72% in the calibration range under different temperatures are always straight lines. The measured values and standards of any standard samplesThe difference of the standard value shall not exceed ±0.02% stipulated by the national standard.In similar instruments;

● sensitivity: 16-bit precision, that is, the minimum discernable reflectivity change of 0.00005%, far better than the national standard provisions of 0.01%;

● filter: measure the main peak at 546nm and the half peak width at 8nm.

● measurement area: measurement area of 2 microns, has been the smallest of similar equipment, the quality group of measurement mirror more pure;

● dark current: corrected, 0;

● stability: similar instruments;When gadolinium gallium standard sample was measured at 23℃, the range of single point fluctuation within 640min was 0.005%, far less than the national standard of no more than 2% (equivalent to 0.034%) within 30min.

● overall dimension: 800mm×100mm×600mm.

● weight: 30kg.
