Based on the principle of liquid-liquid replacement method, the instrument realizes automaticdatacollection, analysis and calculation through an integrated system, and is suitable for measuringthepore size distribution of ultra-filtration membranes and micro-filtration membranes.



The liquidfluxof the membrane is calculated from the trans-membrane pressure and the corresponding liquidflowrate. With the rapid development of the membrane industry, the membrane pore size and fluxanalyzerwill become a necessary professional instrument for colleges and universities, scientific researchinstitutes, production enterprises, environmental protection, measurement, quality inspectionandother related units. , metal and other membrane materials, product development, productionqualitycontrol, use failure.

Product Introduction:



In order to better protect the safety of sampling personnel and provide a comfortable working environment, our company has designed a removable nucleic acid sampling isolation box, which can provide a safe sampling space for testing person.



The Infectious Disease Portable Test Sampling Booth protect positive pressure and directional airflow protection for tester during the nucleic acid sampling. Negative pressure keeps aerosol contained in booth with options for single-pass booth. By providing containment using airflow to capture and exhaust out aerosols from sputum expectoration, handling, sampling or swabbing of asymptomatic carriers, patients under investigation that have some form of COVID-19 symptoms which are borderline to other infectious diseases, COVID-19 positive pa.



Complied Standard:

ISO Class 5 air cleanliness (as per ISO 1464)



Performance character：

1) Ultraviolet disinfection, can be timed.

2) Equipped with primary filtration device and anti-virus high-efficiency air filtration system, the

filtration efficiency of 0.3μm particle size particles is ≧99.995%.

3) Bracket casters, easy to move.

4) The cavity is designed with positive pressure, and the positive pressure in the warehouse is ≧20pa, which prevents external bacteria from flowing into the cavity.

5) The air supply volu.

6) The cavity is controlled by constant temperature, with dual-system air conditioners.

7) Equipped with transfer window (ultraviolet sterilization, mechanical interlock), the size can be

customized.

8) Double-station operation, more convenient and use.

Walter Sweating Fabric Manikin (Walter Sweating Fabric Mannequin) is a new generation of smart sweating fabric manikin developed by Qinsun and famous professors from The Hong Kong Polytechnic University. It is a Simulation of perspiration in sweating fabric manikin an important tool for objectively and accurately evaluating thermal comfort or pressure.



Since the development of the first non-sweating, single segment copper thermal manikin by the US Army in 1940s, there have been numerous developments worldwide in thermal manikin technologies. Nevertheless, the simulation of perspiration has continued to be one of the major challenges. Inspired by the thermoregulation system of the human body, a novel sweating fabric manikin nicknamed “Walter” has been developed in Hong Kong Polytechnic University. The new sweating manikin achieved perspiration over the entire body and a very high measurement accuracy (viz. a CV of less 5%), yet with a cost of only a small fraction of other sweating manikins developed so far.



The improved Walter Sweating Fabric Mannequin has been used to study the influence of walking motion on clothing insulation and evaporation resistance, including improved "walking motion" simulation, design and construction of automatic water supply, and real-time measurement by adjusting the pump inside the human body Evaporate water loss and regulate "skin" temperature. Tests on commercial clothing suits show that the measurement of clothing’s thermal insulation and moisture resistance has good repeatability, and the coefficient of variation is generally less than 5%. In addition to heat insulation and moisture resistance, the percentage of moisture accumulation in clothes is a very useful parameter to measure the comfort of clothes.
