1 Overview

Portable rapid oil fume detector(hereinafter referred to as the detector) is a high-precision portable integrated multifunctional oil fume detector, mainly used to collect the concentration of oil fume emissions in flues and chimneys. Stable performance, easy operation, compact and portable, stable flow rate, can directly test oil fume related data on site, greatly reducing labor intensity. Suitable for fixed flow sampling and concentration measurement of oil fume in fixed pollution sources, as well as temperature, humidity, dynamic pressure, static pressure and other working parameters and measurements of smoke, to evaluate the concentration of organized emissions of oil fume. It is widely used in restaurants, canteens, hotels, environmental monitoring stations, universities, research institutions, urban law enforcement teams and other places to detect the concentration and working parameters of oil fume emissions.

3 Main Technologiesindicator

4 Working conditions：This product is suitable for working under the following environmental conditions

4.1 Working environment temperature: (-30~50)°C

4.2 Relative humidity of working environment: ≤ 85%

4.3 Atmospheric pressure: (80~105) kPa

5 Working principle：The laser scattering method is used to measure the concentration of oil fume in real time. During the sampling process, when particles in the sampled gas are collected by a light source (laser) or other beam, light scattering occurs. The scattered light is converted into an electrical signal (pulse) by a photoelectric sensor. The larger the particles, the larger the pulse signal (peak value). The concentration of each particle size can be obtained by the peak value and number of pulses at this time. By testing the quantity and intensity of scattered light, real-time test data can be obtained.
