The special power supply for atmospheric and smoke dust samplers is used in the field environment detection and sampling. Due to the frequent climbing of chimneys of tens of meters high for sampling and some other factors such as the geographical environment, the power consumption for on-site detection and sampling will be limited, sometimes for To meet the needs of on-site sampling, generators are often used to generate power. The voltage generated by self-contained generators is often unstable, and the frequency is not necessarily a pure 50HZ sine wave. Many sampling instruments have higher requirements on power supply voltage stability and frequency. high. Unstable voltage, frequency other than 50HZ, etc. will cause inaccurate sampling results, and the generator is bulky, heavy, and inconvenient to carry, which seriously affects the work efficiency, and even the instrument is damaged due to the unstable current and voltage of the generator. Even in the case of commercial power, it is sometimes troublesome to obtain electricity on site. Long cables are required, wiring is required, the detection sampling point is far away from the power collection point, the cable is not long enough, and the on-site power supply is interfered by various factors. Serious harmonics and other reasons will also affect work efficiency and sampling accuracy.

Miyang P series AC and DC mobile power supply came into being, with built-in high-quality environmentally friendly lithium-ion batteries, making the power supply lighter in weight, smaller in size, larger in capacity, more convenient to carry, and more efficient and labor-saving to use.
