Constant and wet weighing system ushers in upgrade, weighing accuracy continues to improve

　　Pharmaceutical Network Market Analysis : Recently, there are pharmaceutical equipment enterprise personnel said that the company has another batch of constant temperature and humidity weighing system according to the quality of the scheduled shipment, sent to various testing units The system overcomes the influence of the symmetry result of the temperature and humidity change in the laboratory environment and improves the accuracy of weighing
It is understood that from March 1, 2018, the new standard for environmental protection, "fixed pollution source exhaust gas low concentration particle measurement method " (HJ836-2017)" was officially implemented At the same time, the Ministry of Environmental Protection of the State of China has revised the method of particle determination and gaseous pollutant sampling in fixed pollution sources (GB/T16157-1996), which has also been implemented with HJ836-2017
The implementation of the new standard of environmental protection testing, the constant temperature and humidity equipment put forward a new requirement, the current market of ordinary constant temperature and humidity weighing system can not meet the requirements of national standards It is understood that the enterprise from the end of 2018, in response to the national new standards HJ618-2011, HJ656-2013 and HJ836-2017 "fixed pollution source exhaust gas low concentration particle measurement weight law" requirements, the development of new products constant humidity weighing system to meet market needs
The newly developed thermostatic constant wet weighing system can meet the requirements of the new standard HJ836-2017 "Fixed Pollution Source Low Concentration Determination Weight Method" on the weighing conditions after sampling, place a high-precision balance in the constant temperature and humidity environment, and place the sample of the weighing into the constant temperature and humidity box after 24 hours of balance
Compared with the traditional constant temperature and humidity weighing system, the new product solves the effect of the change of laboratory ambient temperature and humidity on the sample weighing results, and can also be used for sample weighing with higher requirements in other symmetrical environments, with the advantages of high constant humidity control accuracy, high system stability process and humanized design
In recent years, with the continuous development of the environmental testing market, as well as the Ministry of Environmental Protection series of new standards released, some domestic equipment manufacturers with strength are also actively in accordance with market demand, innovative technology, the development of products suitable for market demand At present, the market has manual, semi-automatic and automatic constant temperature and humidity weighing system, can meet the needs of various types of environmental testing units, environmental monitoring stations
The author also learned that, with the development of intelligent technology, some domestic manufacturers are also actively trying to apply intelligent technology to constant temperature and humidity equipment For example, some manufacturers have recently launched a new product intelligent constant temperature and humidity test box, the equipment is mainly aimed at electricians, electronic products, as well as its original devices, and other materials in the high and low temperature, wet and hot cycle environment storage, transportation, use of adaptive tests
According to the introduction, the equipment in accordance with national standards or user-defined requirements, in the high and low temperature humidity cross-change cycle conditions, the physical and other related characteristics of the product after environmental simulation testing, through testing to determine whether the performance of the product can still meet the predetermined requirements, in order to product design, improvement, identification and factory inspection
One of the highlights is that the device uses the human-machine dialogue operation mode, imported full-color touch screen temperature and humidity controller Realize fixed values, loops, programs, etc automatic operation The curve of the running data can be saved automatically or controlled remotely by the computer With bit adjustment and AI artificial intelligence adjustment function, 0.2 level accuracy, a variety of alarm modes Heating, cooling, humidity, constant temperature, constant humidity, the unique BTHC balanced temperature control
Industry said that market demand is constantly changing, equipment manufacturers need to grasp the market trends, while keeping up with the new policy and new standards, keep pace with the times, constantly update and upgrade equipment, in order to meet market demand, seize the opportunity for development.
