放大器将提高 pH 读数的准确性,就像温度计增加有关温度的计算一样。为了精确测量溶液中酸度、碱度和中性的含量,该组件将确保电压计数在 0–14 的 pH 范围内。温度计探头一些 pH 计可以测量被采样溶液的温度并将该信息纳入仪表读数(溶液的温度直接影响 pH)。此功能称为“自动温度补偿(ATC)”。 pH计操作程序 让...

Fig. 1: a Working principle of the switching of the pH-responsive superwetting surface properties between superhydrophobic and superhydrophilic as a function of the pH. The percentage of AEPTMS is 10% on silica nanoparticles with sizes of 15, 50, and 200 nm. The CA of a water droplet de...
Fig. 6. Principle of the scan conversion algorithm. (a) Scanning geometry and motion of the mirror. (b) Angular distribution of the acquired scanlines and angle profile linearization. (c) Effects of mirror declination in volumetric imaging. Since the elevational and zenithal tilting of the mirro...
as specified in the Section 3, with 2N NaOH solution and 2N H 2 SO 4 solution. The pH control was operated by a pH meter (PC310, Suntex Cp., Taipei, Tai- wan) connected to the data acquisition and control (DAC) system. The DAC system consisted of an IBMPC compatible computer ...
The work describes the development of a flexible, hydrogel embedded pH-sensor that can be integrated in inexpensive wearable and non-invasive devices at epidermal level for electrochemical quantification of H+ ions in sweat. Such a device can be useful f
Principle This method is based on the study of the motion of uncharged oil drop under free fall due to gravity and charged oil drop in a uniform electric field. By adjusting uniform electric field suitably, a charged oil drop can be made to move up or down or even kept balanced in the...
tomato DC3000 (non phaseolotoxin-producer), show a retardation signal identical to that obtained with our working strain, indicating that the protein binding to the phtD promoter region is encoded outside of the Pht cluster and is not exclusive to the phaseolicola pathovar, given its presence ...
In principle all monitored boreholes have cathodic protection and an increase in pH might be antici- pated on all drill sites. However, for this to happen, the pull rod has to lack Teflon coating or the coated metal surface has to be damaged. If the current is picked up by the rod ...
and wherein the potentiometer assembly and thermodynamic temperature compensation is substantially similar in principle to that of Figure 1 with the exception of certain changes in the circuit necessitated by the additional functions to be performed. This embodiment includes a potentiometer assembly designat...
