Overview of pH pH generally refers to the hydrogen ion concentration index. Hydrogen ion concentration is a method of expressing hydrogen ion concentration. It is the negative value of the common logarithm of the hydrogen ion concentration (activity) in aqueous solution, that is, -lg[H?]. The determination of hydrogen ion activity index can be qualitatively determined by using pH indicators and pH test paper, while quantitative pH measurement requires the use of pH analyzers or pH meters....
Overview G thread and NPT thread are two common thread types, each with different characteristics and applications. G thread is a British cylindrical pipe thread, mainly used for connections between non-threaded sealed pipes, pipe fittings and pipeline instruments, so it is also called a non-sealed thread pipe thread. It has no sealing function by itself, but can be used with other sealing elements to achieve sealing. NPT thread is a US 60-degree tapered pipe thread, mainly used in North...
