    Q1: How to use the handheld particle counter?
    A1: The particle counter is simple to use, first determine the number of test points according to the area of the clean room and distribute the test points evenly in the clean room, then set the measurement time, measurement unit, flow rate, and other parameters of the particle counter, then put the particle counter on the plane of 1~1.2 meters height from the ground in the middle of the sampling point, and finally start to test the sampling and record the data one by one.

    Q2: How to change the printing paper of the particle counter?
    A2: Generally, the printing part of the particle counter has a cover, some covers can be lifted directly to cover, lift it to replace the printing paper, and some need to use a screwdriver to unscrew the screw, the specific instructions are also introduced, open the cover to follow the thermal printing paper can be replaced.

    Q3: How to read the dust particle counter?
    A3: The results of the dust particle counter, generally the left column is the particle diameter, and the right column is the number of particles per cubic meter.

    Tips: Precautions for using the dust particle counter.

    1. Do not start the counter when the inlet tube is covered or blocked.
    2. The particle counter should be used in a clean environment to prevent damage to the laser sensor.
    3. Do not measure a gas mixture (e.g., hydrogen and oxygen) that may produce a reaction. This gas may also produce an explosion in the counter. Measure these gases need to contact the manufacturer for more information.
    4. Do not sample compressed air without high-pressure decompression equipment (e.g. high pressure diffusers), as all particle counters are designed to operate at one atmosphere.
    5. Water, solutions, or other liquids should not enter the sensor through the inlet tube.
    6. Particle counters are primarily used to test cleanroom clean environments and must be kept at least twelve inches away from the inlet tube when measuring areas with loose particulate material, dust sources, and sprays. In order to avoid the above particles and liquid pollution sensors and pipelines.
    7. When taking samples, avoid taking samples from the counter itself or being contaminated by the gas coming out of the counter.
