Instrument Description:

5E-MIN6150 intelligent nitrogen oven

Size and power consumption is only 1/4 of the traditional oven, can pass nitrogen analysis for arbitration.

Adapt to all coal, used in stainless steel oven arbitration nitrogen analysis. Water is one of the most important indicators of coal settlement indicators of water directly affects the accuracy of the test results of coal prices, the National Standard GB / T211 "Determination of total moisture in coal method" and GB / T212 "method of analysis of coal industry." were provided for the determination of total moisture in coal, air dry basis moisture.

These two standards are specified, only nitrogen drying method applies to all coal testing, nitrogen drying arbitration analysis standards.

■ Applications

This product has blast oven and nitrogen-oven dual function, suitable for electric power, coal, metallurgy, petrochemical, environmental protection, cement, paper, the geological survey, research institutions and other industry sectors measured coal, heavy oil, coke, ore and other substances moisture analysis.

■ using standard

GB / T212-2008 "method of analysis of coal industry", GB / T211-2007 "Determination of total moisture in coal."

Main features:

A "mini", with oven blast and nitrogen-oven dual function, only 1/4 of the volume of a traditional oven; higher precision temperature control, temperature faster, better insulation, more energy-efficient, energy-saving efficiency is improved by 25%.

2, intelligent control, with leakage and over-temperature protection device; the temperature detection terminal interface.

3, a small space, with less nitrogen, the temperature more uniform, more reproducible test. Stainless steel heating pipe, stainless steel chamber, automatic switch vents.

4, automatic operation at night and rest days, 99 hours and 59 minutes can be set free automatic start, automatic stop the chronograph function, even at night and rest days can easily be tested.

5, with the nitrogen drying apparatus.

Q:The difference between UV Vis spectrophotometry and fluorescence spectrophotometry
UV VIS spectrophotometer consists of 5 components: 1. Radiation source. The continuous spectrum must have a stable and sufficient output power, the use of equipment such as band, tungsten lamp, halogen lamp (wavelength range from 350 to 2500 nm), hydrogen deuterium lamp or lamp (180 ~ 460 nm), or tunable dye laser light source etc.. The monochromator [1]. It consists of the incident, the exit slit and lens system and a dispersive element (prism or grating), is a device used to produce high purity monochromatic beam, its functions include composite light generated from the light source into monochromatic light beams of monochromatic light and separation required. Sample container, also called absorption tank. For a solution of absorbance measurement for quartz glass tank is divided into pools and two, the former is applicable to the ultraviolet to the visible region, the latter is only applicable to the visible region. The vessel's optical path is usually 0.5 to 10 cm. Detector, also known as photoelectric converter. Commonly used are photoelectric tubes or photomultiplier tubes, the latter is more sensitive than the former, especially suitable for detecting weak radiation. In recent years, vidicon or photodiode array is used as detector, which has the characteristics of fast scanning. Display device. This part of the device is developing faster. The higher photometer has a microprocessor, a screen display and a recorder, etc., and displays the atlas, data, and operating conditions.
Q:What are the specific methods of chemical instrument analysis?
Chemical reagents, scales and some glassware are used for the determination.
Q:What does water quality analysis instrument include?
I said I know, by using the situation can be divided into two categories, one is a kind of portable instrument, is a desktop instrument, through the principle to words that can be summarized into two categories, one is a kind of instrument is the electrode, colorimetric instrument.
Q:How do you review instrument analysis?
Surface chemical inertness, that is, the surface has no adsorption or poor adsorption, and can not react with the substance under test
Q:How to take the most accurate total station instrument height?
Mark down from the natural instrument with the plumb line, the vertical ball tip just reaches the ground, and then take the instrument sign ruler of plumb line end to plumb tip distance.
Q:What aspects of the instrument do sales engineers need to know?
Instrument use (the use of the instrument, the corresponding instrument model, the advantages and disadvantages of the performance parameters, etc.)
Q:Which brand is good for chemical analysis instruments?
Unlike glutaraldehyde, formaldehyde reacted with DNA and nuclear proteins, but these reactions were partially reversible. In addition, the ability of formaldehyde to fix lipids is not strong enough to function as proteins linked to lipids.
Q:Analytical instruments, laboratory supplies, agricultural materials, which industry prospects for development?
Shandong Aibo trading services in the fields of life science and technology, including the operation of imported and domestic biochemical instruments, scientific instruments, reagents and other supplies, the main brands including Japan OLYMPUS microscope, TheroFisher centrifuge, ultra low temperature refrigerator, oven, Roche Diagnostics products, the United States Alpha gel imaging system, balance, pH meter and Swiss Mettler-toledo analytical instrument, Japan EYELA series of organic synthesis, drying oven, rotary evaporator, cryogenic device, synthesis device, Shanghai days to gel imaging system, BROOKFIELD rheometer, texture analyzer, American rainin pipettors, American PALL, ultra pure water filtration equipment, Hangzhou bauges gene amplification instrument.
Q:Which instruments are needed or may be used for physical chemical analysis?
Organic compounds are much more complex, and gas chromatography, liquid chromatography, mass spectrometry, and infrared spectrometers are commonly used;
Q:What is the measuring line on the highway? Is it measured by an instrument such as a theodolite?
On line measurement and measurement is different, in general is elevation, instruments or other means of verticality measurement work, put the line is limited to the scope of the construction of buildings, roads, construction plans will reflect to the construction site.Generally use level to determine elevation
