Product modeling and design ability has been greatly improved, but after the completion of product design, before mass production, we must make samples to express the design idea, quickly obtain the feedback information of product design, and evaluate and demonstrate the feasibility of product design. In today's increasingly fierce market competition, time is benefit. In order to improve the competitiveness of the product market, the whole process from product development to mass production is urgently required to reduce the cost and improve the speed. The emergence of rapid prototyping technology provides an effective way to solve this problem, and has attracted much attention at home and abroad Ningbo Rongna Technology Co.,Ltd , https://www.prototyping-machining.com
PHS-3C digital pH meter is an instrument for measuring the pH of a solution. It can also measure the setting and measurement of each parameter value of the electrode potential (mv). It can be switched with a selection switch and has a high-brightness LED digital tube display. The instrument uses composite glass. Electrode, set temperature value also have digital display, and achieve temperature compensation. The instrument abandons the traditional power transformer, using a new type of instrumentation dedicated small switching power supply, so that the instrument has over-current detection throughout the work process, over-voltage, overheating automatically A series of perfect protection functions, such as closing, not only increase the reliability of the instrument, but also significantly reduce the volume and weight. It also enables the long-term reliable and stable operation of the power supply voltage from a wide range of 80V-265V.
