Aerosol Photometer Calibration Solution

What is Aerosol Photometer Calibration?

The aerosol photometer is designed based on the Mie scattering principle. It is an instrument that calculates the filtration efficiency by measuring the ratio of the mass concentration of aerosol particles (PAO, DOP) in the air upstream and downstream of the sample being measured. It has now become an important indicator of the filtration efficiency of high-efficiency filters. As the main equipment for quantitative evaluation, ISO14644-3 clearly states that the aerosol photometer is used to perform performance testing of high-efficiency filters.

The accuracy of the aerosol photometer indication affects the test results of filtration efficiency to a certain extent. For industries such as pharmaceutical companies with higher cleanliness requirements, the calibration of photometers also has higher requirements. Aerosol photometers usually should be calibrated annually. According to relevant standards and specifications, Junray provides an overall solution for aerosol photometer calibration.

What equipment is needed for an Aerosol Photometer calibration?

1, Precision Aerosol Photometer

The ZR-6011 is designed based on Mie scattering principle and is special testing equipment used to calibrate and value the traceability of aerosol photometers. The manual weighing method is used for calibration and value traceability to form a complete value traceability system, which facilitates the rapid calibration of aerosol photometers by third-party testing and metrology institutes.

2, Aerosol Mist Mixing Device

The ZR-1320 aerosol mist mixing device is a device that realizes aerosol mist and dynamic dilution and mixing to produce aerosol with a stable concentration. The working process is to introduce the external dry clean air source into the aerosol-generating device to generate high-concentration aerosol, and the aerosol enters the dilution and mixing chamber for dynamic dilution and mixing. The control of aerosol generation concentration can be achieved by real-time control of the pressure of the aerosol generation device and the fan speed. A high-efficiency filter is installed in front of the inlet to filter out particulate matter in the air, ensure the cleanliness of the gas, and protect the components in the gas path.

3, Portable Flow and Pressure Comprehensive Calibration Device

Adopting the principle of orifice flow measurement and a built-in high-precision pressure sensor, it can be used for flow and pressure calibration of different machines, flow rate calibration range is 10ml/min~1400 L/min, and pressure calibration range is up to 60kPa. It is widely used in environmental monitoring, labor protection, health, scientific research institutions, metrology institutes, and other departments.Portable Flow and Pressure Comprehensive Calibration Device like:
