MAS-100NT microbial air sampler and a smart valve

Air monitoring in some areas become increasingly important, particularly in the pharmaceutical industry, cosmetic industry, food industry and environmental monitoring field. Because microorganisms in the air pollution and the growing influence of the industrial product and its production process, thus affecting human health. The current sampling methods, mostly based on the Anderson impaction principle. In the MAS-100 series of air monitoring system in the development process, the primary goal is to create a compact, easy to operate, reliable, standards-based culture systems can be used. MAS-100NT suction air flow rate is 100 liters per minute. Each collection period, up to 2000 liters of air can be collected. This performance can meet the stringent requirements of the monitoring samples in sterile rooms and clean room carried out. Impact velocity (air impingement microbial agar surface speed) is about 20 m / sec, equivalent to 6 Andersen sampler. This ensures> 0.6 micron particles are collected. NOTE: MAS 100 NT strict accordance with ISO14698-1: 2003 standard design, sampling rate 100L ± 2.5%, dish diameter used is 90-100mm. [Fundamentals] MAS-100 NT is a high-performance instrument. It uses the principle of Andersen air sampler, air is drawn through the porous cover (300 * 0.6mm), a stream of micro-organisms attached to the crash standard dish agar surface. After completion of the sampling period, the culture dish placed under suitable conditions, and then determine the total number of colonies. MAS-100NT operating system, comprising a suction device performance and built-in wind speed meter to continuously monitor the intake air volume. The system automatically detects wind speed and the flow rate at any time to adjust the pumping speed to ensure that the sample volume per minute is 100L. So the system in the face of external factors interfere with the steady flow or because the dish is too full and lead to local intake obstruction, can automatically adjust the sampling rate to 100L / min. In accordance with international table standards, standards for the measurement of the pharmaceutical industry is the amount of microorganisms within one cubic meter. The main advantages of the MAS 100 NT's] standard adapter plate 90-100mm diameter without using expensive "support" for supplies built anemometer flow compensation: The different parts of the injection hole and plugging in the volume of the medium plate will not affect the actual sampling rate and sample volume gas flow rate is too low when prompted sampling time and date display adjustable head support folder to the difference in size for different dishes can be connected to 100 / 240V, 50-60kHz working power supply or battery operation using only the sample volume can be set to any value between 1-2000L applicable RODAC plates (sold separately with) is eligible for certification ISO14698 standard USB communication connection, to ensure the accuracy of the results recorded SQS loop sampling function: By choosing this function key, you can achieve 24 hours Up to 50 consecutive samples fully automatic sampling precision calibration, avoiding manual error all the hardware and software were HACCP (Hazard Analysis and Critical Control Point (English Hazard Analysis Critical Control Point)) Certification
