Dust particle counter parameter difference: 1. Different display, LCD, LED \ 2. AC and DC are batteries and no batteries . There are many suitable rooms without batteries . 3. Classification of domestic dust particle counters: 1. Press Sample flow: 2.83L / min, 28.3L / min , 50L / min, 100L / min, at present these four. 2. Display: LED (the LED), a liquid crystal screen (LCD), color touch screen, three types. 3. Power supply: AC power supply (generally both * 220V) and a built-in rechargeable battery two types. 4. Style: Handheld (1kg or less), a portable (about 5Kg, A4 paper size, 12cm high so), desktop (about 10Kg, more than A4 size) three kinds. Handheld* is a sampling flow of 2.83L/min , portable * is also a sampling flow of 2.83L / min , desktop * is a large flow of laser dust particle counter (flow rate of 28.3L / min can be Called a large flow). At present, the selection of domestic dust particle counters: 1. Generally, the industry recommends using a sampling flow rate of 2.83 L/min , which is the same as the displacement of the car. The larger the sampling flow rate, the more expensive the price, and the smaller the small particle size, the more expensive it is. * General are now mainstream detect small particle size of 0.3 μ m, many domestic standard is currently 0.5 μ m of view, * like enough. 2. In consideration of ease of use, it is recommended to use a laser dust particle counter with a handheld or built-in rechargeable battery. 3. There are currently customers in the pharmaceutical industry. Because GMP requires the detection of 1 cubic meter of dust particles in the air during mobile testing , it is obviously inappropriate to use a 2.83 L/min laser dust particle counter (requires continuous detection for 350 minutes). require at least 28.3L / min of laser particle counter (35 minutes continuously detected), conditional selection of 50L / min (continuously detected 20 minutes) and 100L / min (continuously detected 10 minutes) laser particle counter. The pharmaceutical industry also requires the detection of real-time dust particles in the 100 -level zone. This is the online dust particle detection system, which consists of a laser dust particle detection transmitter, a wired or wireless transmission system, special software, and a computer. The sampling flow rate is 2.83 L/min. and 28.3L / min min's, 2.83L / min online dust particle detection system because it is a built-in vacuum, increasing the detection points at any time after the customer convenience, easy to install, it is recommended customers like * * the election; 28.3L / min online dust Because the particle detection system needs an external vacuum system, it needs to install the process pipeline of the vacuum system. If the customer needs to increase the number of inspection points, it may be due to the insufficient flow of the reserved vacuum system, and the problem of replacing the large vacuum pump and adding the process pipeline.
