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: What is the working principle of the online remote particle counter?
The online remote particle counter works based on the laser scattering principle. When air is drawn into the device, particles pass through a laser beam inside the sensor chamber. As each particle crosses the laser, it scatters light.
A built-in photodetector captures the scattered light signal and converts it into electrical pulses. The intensity of the scattered light corresponds to the particle size, allowing the device to accurately classify and count particles within different size channels.
This technology ensures fast response, high sensitivity (down to 0.3μm), and reliable real-time monitoring for cleanroom and industrial air quality applications.
