FAQ

What tests can be made by a skin test instrument?
Using patented bio sensing principle, the depth of the probe in the epidermis and dermis of the skin with moisture, physical parameters of elastic oil content and the most representative were detected, and calculate the ratio and volume measurement.
How can a leveling measure the height of a instrument?
The instrument of a level is measured by hand, such as tape measure, and, if it is a standard, it does not need to be measured
What is coal quality industrial analyzer, coal quality industrial analyzer, which are the main indicators of coal?
Industrial analyzer is mainly used for analysis in coal: water (water), ash, volatile matter and fixed carbon (calculated), is composed of a heating system (Gao Wenlu), weighing system (balance) and control system (computer) instrument, to replace the old muffle furnace and oven, balance function, can reduce the the influence of the test results;
Notes on the use of oxygen analyzers
The change of oxygen content in sample gas will be affected by pipe material and surface roughness. Therefore, copper pipe or polished stainless steel pipe can be used in general connection line, instead of plastic pipe and rubber tube.
What kind of instrument does a battery company usually use?
YXD-3000 internal battery resistance tester.
Internal standard method, instrumental analysis
Choose a line in the spectrum analysis of the measured element, choose one with its symmetric line in the matrix line, according to this on the spectral line intensity ratio on the content of the measured elements making working curve, and then to the unknown sample by quantitative analysis method called internal standard method.
What indicators are used to measure the merits of a detector in instrumental analysis?
1, linear range, that is, a detector slope remains constant concentration or mass range.2, detection limits, the minimum detectable concentration or quality of the detector.3 limit of measurement, minimum concentration or quality that the detector can accurately measure.4, sensitivity, in GC, refers to the response signal to the sample rate of change, usually refers to the slope of the line.5. Selectivity, in GC, refers to the ratio of the response value of the measured component to the response value of the interference component, which generally refers to the anti-jamming capability of the detector.6, precision, which includes the precision of the method and the precision of the instrument, is usually indistinguishable.7. Stability. In the potentiometric method, the stability is usually indicated by the potential shift of the electrode system under constant conditions.8. Reproducibility. The mean deviation of potential in the potentiometric method when the finger electrode is returned three times to determine the solution with a concentration of 10-3 mol/L and 10-2 mol/L.
What instruments do you need to open a beauty parlor?
This depends on the size of your beauty salons and to carry out the business strategy, if it is a large instrument beauty salon it may need a little more, such as what hair removal ah, fat soluble instrument freckle ah, ah what are is, if it is a small beauty salon would be one or two the instruments on the line, now like the summer, you can buy a hair removal, hair removal instrument you can see Friedrich hair removal instrument Shenzhen jisidi, I personally feel that the effect is very good, and it is simple to operate and easy to use, whether large or small beauty salons are very suitable
