Ash melting point detector for the determination of ash melting characteristics. Silicon carbon tubes the hair temperature components in accordance with GB provides auto-complete determination of ash melting point during the heating process can also be within a certain range of the control parameter selection and modification. Otherwise optional heating program for other heating processes. This instrument also comes with a standard RS232 communication interface, and to prepare for expansion and communication. Microcomputer ash melting point tester using the a WINXP system software, real-time image and the temperature of the ash cone, and draw temperature curve. Microcomputer automatic control heating rate characteristics in line with GB GB/T219 gray taper image automatically save a high degree of automation, and do not need to sit machine observed. Can always view the the gray cone image results. Reduce the labor intensity of the operator, automatically print test results. Furnace multilayer insulation, has a unique effect of the insulation, and has a rotating function. Ultrafine thermocouple design to eliminate image noise, and has a self-diagnostic function. Abnormal, automatically displays the error message, the whole process is fully automated. Technical indicators: Measuring range: 0 to 1600 ° C, resolution 1 ℃ equipped with the S value thermocouple time range: 0 to 999min Resolution 1min heating rate: ≤ 900 ℃ for 15 to 20 ° C / min> 900 ° C for 5 ± 1 ℃ / min measurement error: ± 3 ° C test atmosphere: the oxidizing or reducing power: AC220 ± 10% 50HZ current: ≤ 30A Hebi City Xin Yun equipment Limited 1 Dongjing Li
