The GYW12 series explosion-proof particle counter (contamination sensor) adopts single-laser light-blocking counting technology, featuring fast detection speed, strong anti-interference capability, high accuracy, and good repeatability.
It can accurately detect the particle size and quantity distribution in the tested oil sample. Combined with a Fourier waveform analysis model, it significantly improves the precision of detecting micro-particles and high-cleanliness oils.
It can automatically correct invalid data and interference data.
It also provides excellent improvement against the influence of trace moisture and air bubbles on contamination measurement commonly encountered on site.
