1. Product introduction
JCH-121F intelligent particulate matter comprehensive sampler is a multi-functional sampling instrument integrating TSP\PM10\PM2.5 particulate matter and microorganisms. It is equipped with an international six -stage Anderson cutter to realize sampling and monitoring of air microorganisms. Widely used in disease control, clean laboratory, food, scientific research and teaching, public environmental sanitation and environmental monitoring and other fields.

3. Product Features
1. It has small size, light weight, low noise, high intelligence, stable flow, reliable operation, built-in heater, pictures and texts, and integrates the collection of microorganisms and particulate matter.
2. Adopt imported wide temperature OLED display, good man-machine interface with pictures and texts, easy to operate, humanized Chinese graphic display, can work in ultra-low temperature environment.
3. There are multiple sampling methods such as simultaneous sampling, individual sampling, multiple sampling, every other day sampling, and cyclic sampling , which can effectively prevent the sampling personnel from being exposed to the microbial space for a long time.
4. The imported brushless motor air pump is adopted, which has high reliability for long-term continuous operation, low noise, long service life, and the trouble-free running time is more than 20,000 hours.
5. Real-time clock, with timing sampling, interval sampling, multiple sampling, cyclic sampling and other sampling methods for users to choose and use.
6. Automatically save data during AC power failure. Automatically resume sampling when AC incoming calls, automatically deduct the power-down time during the sampling process, and allow users to query the power-down time.
7. The sampler is designed with an automatic save function, which will be used first when it is turned on next time. Automatic fault protection function, automatic shutdown protection if the set flow rate is not reached within the specified time.
8. The instrument can be equipped with a built-in large-capacity imported lithium battery, which can work continuously for a long time in places without AC power.
9. Optional Anderson level 2 , level 6 , level 8 cutters and impact absorption bottles, with a sampling flow rate of 28.3L/min ;
10. Automatic flow control , embedded software design, automatic calculation of sampling volume, automatic memory of sampling data, priority use next time it is turned on, and one-click sampling.
11. Standard TSP, optional PM10 , PM2.5 , PM1 , cutters are made of aluminum alloy, anti-static adsorption.
12. Standard time, delay time, sampling time, sampling times, cumulative flow, instantaneous flow, atmospheric pressure and other parameters
show.
13. The user can calibrate the instrument through the keyboard. Maintenance requires a password to enter to ensure the security of the instrument data and will not be easily accessed.
Modify the error, and provide the function of restoring the factory settings.
14. The optional RS232 interface is connected to a micro-printer for data printing, and it can also be exported through a U disk and the host can automatically identify the capacity of the U disk.
