but for the double pan balance, a container which is the same as the container to be weighed can be placed on the opposite pan. By weighing the two as the mass of the container, the two weighing shall be completed in the shortest possible time to ensure weighing under the same conditions. The air temperature and atmospheric pressure in the balance room shall also be recorded. It should be carried out carefully and quickly so as to reduce the error caused by evaporation loss. The balance used shall be in good working condition. The outside of the weighing gauge shall be cleaned and handled carefully to prevent pollution. It can be wiped with clean cotton cloth in code for design of automatic sprinkler system gb50084 ⑵ 001 as required, and taken with clean cotton gloves. The difference between the mass of the load-bearing container IL and the mass of the empty container ie is the apparent mass of the incoming or outgoing water measured by the gauge to be calibrated, and then the capacity is calculated according to the corresponding formula. (1) Glass instruments that can be directly heated: test tubes, glass rods, crucibles, evaporating dishes, etc. (2) Glass instruments that cannot be directly heated by alcohol lamp and can only be heated after asbestos is placed on them: beakers, flasks (round bottom and flat bottom flasks), distillation flasks (round bottom and flat bottom distillation flasks) and conical flasks

what are the temperature fatigue testing machines? The temperature in the test chamber decreases from normal temperature to -40 ± 2 ℃ at the rate of 5 ℃/min, and it will be stored for 48 hours after the temperature reaches stability; 6) Take the tested terminal out of the test chamber and recover it at room temperature for 2 hours, and then conduct appearance, assembly and function inspection. It is required that the appearance, assembly and function are not significantly different from those before the test; Inspect the appearance and function of the tested terminal at normal temperature; Put the prototype in the shutdown state into the temperature impact test chamber. The prototype is stored at -40 ℃ for 1 hour. Within 5 minutes, the temperature rises to 60 ℃ for 1 hour. This is a cycle. The prototype is tested for 10 cycles in total; 9) Take the tested terminal out of the test chamber and recover it at room temperature for 2 hours, and then conduct appearance, assembly and function inspection. It is required that the appearance, assembly and function are not significantly different from those before the test; 10) Inspect the appearance and function of the tested terminal at normal temperature; 11) Insert the user card into the startup state of the prototype to be tested, and put the T-Flash card into the temperature test chamber

instrument calibration institution Shitong Instrument Testing Service Co., Ltd. is a third-party fair laboratory recognized by the China National Accreditation Service for Accreditation (CNAs) and specialized in providing instrument measurement, instrument calibration and instrument calibration for enterprises. The calibration/statements are in line with the requirements of iso/iec2005 instrument calibration and testing laboratory. The company also has Guangdong Dongguan instrument calibration laboratory and Jiangsu Kunshan instrument calibration laboratory. Among them, Dongguan Shitong instrument calibration laboratory has a registered capital of 10million yuan and a national CNAs approval number of l3170. Jiangsu Shitong instrument calibration laboratory has a capital of 10million yuan and a national CNAs approval number of l6634. The actual investment capital exceeds 30million yuan. Both of them have established standardized departments, and the laboratory covers an area of nearly 10000 square meters, Through the national cna, it initiated 500 entity sharing mode s recognition projects. Danzhai surveying and mapping instrument calibration institution private enterprises have stepped on the stage of the tension machine industry. In recent years

Ma Yun once said at the "2016 Zhejiang Merchants' economic situation analysis and judgment meeting" that it is better to take shelter from the rain when the storm comes. However, Nie always has his own opinion. He believes that it is not advisable to take shelter from the rain for six years. In some cases, we are allowed to move forward in the rain, while in some cases, we need to take shelter under the eaves. We should size up the situation and adjust our actions at any time. Stick to the promise and continue to be optimistic about the Chinese market. "Although the market has been stagnant for six years, the Chinese market is still an important business core of Hengyu instruments. We will work with customers and partners to realize the solid commitment of Hengyu instruments and jointly build a trusted tensile testing machine brand in South China." in 2016, China's tensile testing machine industry is still facing difficulties and hopes, with the challenges of increased market ownership and structural overcapacity, There are also good opportunities for the construction of new urbanization, the national "the Belt and Road" strategy, international production capacity cooperation, the coordinated development of Beijing, Tianjin and Hebei, and the construction strategy of the Yangtze River economic belt
