Main features:

1, the instrument before each use without correction, can be measured every 30 seconds of a point, and fast!

2, portable, one person may operate during the operation have voice prompts.

3. Use the LCD backlight display the operation screen, can be operated at night, on-screen display as follows:

Gray scores:. ×× ×%

Heat:. ×× × MJ / Kg

Energy value:. ×× × Kev

4, may be infrared transfer of data to the PC, or printer.

5 for more coal testing, you can save 50 coal characteristic parameters of the instrument.

6, security, this instrument only within 30 seconds, without any damage to the operator.

Q: What is the difference between modern instrumental analysis and chemical analysis methods?: The function of the instrument to replace some artificial action, five concept identification and human, to speed up the progress of the analysis, to reduce the number of human errors; but if the principle is the use of new technology to achieve detection, then the determination object may be different, the determination of some heavy metals such as traditional chemical methods, may require chemical titration reaction each other through a variety of substances to judge analysis, a large number of samples needed before processing can be realized, but modern spectral instruments can realize nondestructive testing, do not need to complete the reaction through the middle to qualitative or quantitative, also do not need to sample pretreatment.

Q: What are the advantages and disadvantages of instrumental analysis compared with traditional methods?: The disadvantage of instrument analysis is that the instrument is expensive, difficult to popularize, and the accuracy of constant analysis is low.

Q: How do you understand the performance indicators of an analytical instrument: dynamic range? How do you understand the following diagram?: In the linear response limit above the measured signal, it is necessary to change the "sampling amount" and other measures, so that the measured signal in the linear range before you can calculate the results reported

Q: Analytical instruments used in the chemical industry, if possible, specify specific industry instruments: For example, the Undergraduate Teaching Steering Committee of the Ministry of education puts forward the following basic requirements for the configuration of instrument analysis experiment, which can serve as a reference for laboratory construction.Equipment must be equipped with: visible spectrophotometer, UV visible spectrophotometer, infrared spectrometer, atomic emission spectrometry, atomic absorption spectrophotometer, gas chromatography, high-performance liquid chromatography, electrochemical workstation.

Q: How can a leveling measure the height of a instrument?: Do not need to know the instrument level is high, the level is just a horizontal line of sight through the horizontal line of sight on forward rear view of reading difference to obtain the difference between before and after treated, the trigonometric leveling instead of four water standards requirement of equipment, is to measure the total station, from the following points to the lens axis, the instrument has marked

Q: What is the basis for building an analytical instrument?: There are different effects in different parts, and then the signal conversion system, the atomic absorption of light, we detect the intensity of light is not absorbed, the detector for photomultiplier tube, through signal amplification, digital analog conversion to obtain the transmittance or absorbance, directly on the instrument display can be read. In fact, this part contains the amplified recording and readout device. Different instruments are similar. A well please correct me.

Q: Instrumental analysis can be used for porcelain dating: It is the use of porcelain in the day it was burned, it will continue to absorb and accumulate the external radiation energy, this energy and burning after the length of time. The time of porcelain can be known indirectly by measuring radiant energy. Thank you

Q: Could you tell me the error range of carbon and sulfur analysis?: Main technical performanceWith humanized design, the structure and control panel are all produced by modern processing technology. The products are precise, beautiful and generousThe micro processing unit adopts the most popular ARM9 system at present, and integrates the dual communication interface of high speed USB and Ethernet TCP/IP protocolIn our country, we adopt linear calibration software of multiple nonlinear fitting techniques, single point fitting and multi-point Fitting CorrectionA high performance pyroelectric infrared sensor based on lithium tantalate was used to improve the sensitivity of the systemConstant voltage and constant current of gas path system and stability of analysis dataAdopt 3 5KW, air cooling ceramic power tube, heating power is stable and reliableHigh frequency furnace power adjustable, suitable for different materials, sample analysis requirementsThe automatic cleaning device can reduce the influence of dust on the analysis resultThe furnace heating device makes the conversion rate of sulfur more consistent, and improves the stability of sulfur determination

Q: The coal analyzer there is better: Henan, Hebi City, there are many manufacturers of coal quality testing instruments, and they are all good.

Q: With regard to the inspection of petroleum products, which one of the analytical instruments is of good quality?: Best to go a few large oil products inspection units, research, and then make a decision.
