The plankton sampler can be equipped with a special triangular bracket and the sampling height can be adjusted. Compressed gas sampling nozzle can be selected, and 8bar pressure-preserving sampling can be carried out with high pressure control. Instrument air suction device will be through a porous sample head suction, hit the Ф 90 mm petri dishes, in the air was "captured" on AGAR medium. It is an efficient porous suction sampler based on the Anderson impact principle with an impact velocity of 10.8m/s, equivalent to the fifth level of the Anderson impact rating. Standard impact sift-hole working mode, equivalent to the fifth stage of Anderson impact level tip air flow sensor, constant current sampling, high flow control accuracy. Automatic shutdown due to low power or flow error exceeding 2.5%. Automatic measurement of ambient temperature and atmospheric pressure, flow with the change of temperature and atmospheric pressure automatically maintain constant current. Dot matrix LCD, Chinese menu operation, real-time clock display. Use real-time conversion function of environmental parameters without recirculation calibration at any temperature, altitude and atmospheric pressure. It can be widely used in pharmaceutical industry, food industry, beverage tap water, drug inspection, health and epidemic prevention, public places and other relevant industries and departments.



Some important points to note before packing or transporting plankton sampler:



1. The surface of the machine can also be wiped with alcohol or water.



2. Be careful not to splash water into the circuit or electronic connection.



3, surface dirt with a soft cloth dipped in about 70 % alcohol or water or other commonly used disinfectant wipe.



4. Perforated cover and dust cover can be sterilized at high temperature and pressure (15 min /121℃) 6.5.3 Note that the holes of the perforated cover are not blocked.



5. Calibration of sampling results: First, the count of microcolony shall be calibrated by Feller statistical calibration table (see the attachment), and then converted into the number of pollution particles per cubic meter. The principle of the correction table is that as the volume or number of samples increases, so does the probability that two or more microarrays will enter the petri dish through the same hole.



6. Regular calibration is required.
