But a pH meter somehow has to measure the concentration of hydrogen ions. How does it do it? An acidic solution has far more positively charged hydrogen ions in it than an alkaline one, so it has greater potential to produce an electric current in a certain situation—in other words, it...
pH is a measure of hydrogen ion activity in aqueous solutions. In pH, the p is –log10and the H is hydrogen ion activity. Therefore pH = -log10aH+, where a is the activity of the hydrogen ions, which also may be considered the hydrogen ion concentration. This is alogarithmicscale, an...
Zhurong's solar wings are also equipped with directional sun-tracking capability which enables the rover's wings to shift as the sun rises, like those of a sunflower, to maximize solar energy absorption despite the low angle of the sun during the winter. The third measure ...
If use a probe to measure the DC output, it can cause ground return current which will affect the measurement. Because of that, ground return should be avoided. Using a differential oscilloscope or oscilloscope with a external differential amplifier is the correct method for testing connection, ...
But there's a simple way to measure magnetism with a device called a Hall-effect sensor or probe, which uses a clever bit of science discovered in 1879 by American physicist Edwin H. Hall (1855–1938). Hall's work was ingenious and years ahead of its time—20 years before the ...
Figure 7:You can pair NI oscilloscopes with the NI LabVIEW Jitter Analysis Toolkit to perform signal integrity measurements within NI LabVIEW. Back to top What is the Difference Between an Oscilloscope and a Digitizer? If you require more customizability than an oscilloscope, such as in-line FPGA...
Using a large range, you could measure the large signal but the tiny signal would be in the noise of the large signal. On the other hand, if you use a small range, then you’d clip the large signal and your measurement would be distorted and invalid. Thus, for applications that ...
Object creation/reclamation rate.This is a measure of the rate at which instances are created or reclaimed in an application. The higher the object creation rate, the more frequent GC cycles will be, consequently increasing CPU utilization. ...
Most homebrewers measure the pH of a cooled mash sample when checking pH. While pH meters are able to measure the hot mash pH it is not advisable to do so because it shortens the life of the probe. If colorpHast strips are used in the hot mash, their color reaction is the same or...
How to test Latency with a Ping command A question that people often ask is "How do I measure network latency using command-line tools like ping and traceroute?" Lucky for you, these two tools are the easiest ways to quickly test latency. While they don't give you complete diagnostics...
