F9310 Aerosol Photometer Calibration Device

Purpose
The aerosol photometer calibration device is a testing device used to calibrate various parameters of the aerosol photometer. The calibration device can calibrate the aerosol photometer's sampling flow rate indication error, sampling flow repeatability, sampling flow stability, mass concentration indication error and zero point drift.
Features
●Automatically generate accurate calibration point concentration;
●With the calibration function of the precision aerosol photometer (measurement standard);
●It has two concentration calibration methods of comparison and weighing, with self-checking function;
●The equipment is equipped with a regulated power supply, which will not interfere with the precision photometer and the inspected instrument;
●Fully automatic touch screen operation, can automatically generate calibration report, well equipped with printer, can be printed on site;
●The filtration system adopts secondary filtration to ensure that the equipment discharges clean air to the environment and achieve zero pollution discharge;
●The system control adopts industrial control computer and capacitive touch display, with high control precision and flexible and convenient operation;
●Using a hierarchical generating device, the produced aerosol concentration range is wide, the accuracy is high, and the stability index at high and low concentrations is higher than the national standard.

principle

This device is composed of aerosol generator, mixing system, flow reference and concentration calibration system. It uses the aerosol generation system to provide a quantitative supply of test particles, and uses uniform dilution, diffusion, stabilization, etc. to transport aerosols with a set concentration, and adopts aerosol photometer mass concentration standard device (reference photometer) or filter film to weigh Law as a traceability method.
