Abstract: A light scattering particle counter that improves the signal-to-noise ratio by attenuating the high frequency noise component while suppressing the attenuation of the signal component by irradiating a sample fluid with a laser beam La to form a particle detection area, detecting a particle with a multi-channel light detecting element that receives scattered light Ls from a particle passing through the particle detection area, and with low pass filters having time constants ?c, ?m, ?e that are set to depend on beam diameter of the laser beam La and flow velocity of the fluid which flows through each divided area, to count particles in the sample fluid.

[Means for Solving the Problems] A light scattering particle counter which irradiates a laser beam La to a sample fluid and forms a particle detection area 13, a multi-channel light detecting element receives scattered light Ls from a particle passing through the particle detection area and detects the particle, the time constants ?c, ?m, ?e of the low pass filters F1, F2, F3, F4, F5 are set depending on the beam diameter of the laser beam La and the flow velocity of the fluid which flows through each divided area.

Abstract: A particle counting method that can count the number of the particles precisely. The method discriminates a wave pattern of the scattered light from a normal particle (subject of the counting) and a wave pattern of the light scattered by the agitation such as a floating particle, a radiation or changes in the intensity of the light. In one embodiment, a method for counting particles is disclosed which irradiates a light to a sample gas, detects a scattered light from a particle included in the sample gas by a photoelectric conversion device, counts the number of the particles of every particle size division by the output voltage wave pattern of the photoelectric conversion device, calculate a time difference (Ta?T1) from a point (T1) being a peak of output voltage wave pattern and a point (Ta) being a falling detection threshold (A), when the time difference (Ta?T1) is beyond counting cancellation time (B), the output voltage wave pattern is not counted as a particle.

Abstract: A humidity meter includes a humidity-frequency converter which is essentially a pulse oscillator, the frequency of which depends upon the impedance of a humidity sensor, a pulse width modulator for adjusting pulse width of an output pulse of the converter for assuring a linear relationship between humidity and the output signal, and an integrator for integrating the output of the pulse width modulator to provide an output signal as a DC level. A feedback path is provided to apply the output signal to the pulse width modulator for assuring a linear output irrespective of the exponential characteristics of the humidity sensor.
