Based on the relevant theories and standards of performance calibration testing of particle counters and dust detectors, the dust generator is a device that can generate a specific concentration of dust particles. It is commonly used in dust particle counters and dust detector calibration benches. Qingdao Minhope Electronic Instrument Company (hereafter: Minhope) has chosen the Palas® classic RBG 2000 dust aerosol generator as the core product of their calibration test bench. The stable dust concentration and good compatibility of the RBG 2000 facilitate the development of Minghua Electronics’ environmental monitoring and analysis equipment and calibration test stands.
Palas® complete solutions for environmental monitoring and analysis
Qingdao Minhope Electronic Instrument Co, Ltd. is a high-tech company specialising in the research and development of various instruments and devices for environmental monitoring and analysis. The company uses advanced information technology to transform traditional instruments and devices, providing a complete set of environmental monitoring equipment and total solutions that combine software and hardware and integrate management and control. The company’s research and development achievements have passed various management system certifications and have been involved in the formulation of a number of industry standards, as well as the specific research and development of major national instruments.
Since the dust generator before Minhope is mainly based on the principle of spiral ring dust generation, it is easily influenced by environmental factors such as relative humidity, which leads to dust agglomeration. As a result, the stability of the generator’s dust generation cannot reach the ideal test level. Therefore, Minhope Electronics has been searching for a suitable dust generator to optimise the existing test and calibration scheme. Through lively exchanges between Palas® manufacturers and partners in Shandong, Minheop has come to the conclusion that the dust generation method, in which the dust is brushed in the powder hopper, is less susceptible to environmental influences. At the same time, the larger mass flow range is also more in line with the company’s own needs. This is why Minhope chose the Palas® RBG 2000 as the centrepiece of the calibration test rig. Those responsible at Minhope commented: “The Palas® aerosol generator in Germany is highly regarded in the measurement and calibration industry and the stability and accuracy of the dust generation fully meets our requirements, so we opted for the Palas® solution”. Palas®’s professional and prompt communication and quick-response technical support are also appreciated by those responsible at Minhope.
RBG System Aerosol Generator
Low concentration solid aerosols generated from dust and powder are suitable for many applications. For example, for research, development and quality control of calibration test stands for particle measuring instruments. The stability of the generator’s single dust generation and the lower feed rate are necessary prerequisites for the generation of low-concentration solid aerosols. In addition, the reproducibility of the aerosol generation process must be guaranteed. The RBG system can fulfil the above-mentioned relative phase requirements in the mass flow range of 0.04 g/h – 800 g/h.
For mass flows from 40 mg/h to 800 g/h, the three new aerosol generators RBG professional, RBG basic and RBG solo meet all current requirements in many areas – from research to quality assurance and calibration. The dust or powder-filled reservoir is fed by state-of-the-art stepper motor technology, which ensures precise feeding to the dispersing brush over a wide mass range. The RBG professional is also designed to be pressure-resistant up to 10 bar and is equipped with automatic volume flow control. This ensures high stability of the dispersion performance over a wide range of applications, even with fluctuating supply pressure. A pump for supplying carrier air is built into the RBG solo. This means that the unit can be used anywhere without a compressed air supply. All models also offer the option of remote control via a PC with the Palas® RBG Control software included in the scope of delivery.
Palas® has now launched the new RBG aerosol generator, three aerosol generators RBG Professional, RBG basic and RBG solo to meet the requirements from research to quality assurance and calibration.
