F9310 Aerosol Photometer Calibration Device
The aerosol photometer calibration device is a detection device used to calibrate various parameters of the aerosol photometer. This calibration device can calibrate parameters such as sampling flow rate indication error, sampling flow rate repeatability, sampling flow rate stability, mass concentration indication error, and zero drift of the aerosol photometer.
Features
● Automatically generates precise calibration point concentrations;
● Has the calibration function of a precision aerosol photometer (metrological standard instrument);
● Has two concentration calibration methods: comparison and weighing, and has a self-check function;
● The device is equipped with a stabilized power supply, which does not interfere with the precision photometer and the instrument under test;
● Fully automatic touch screen operation, can automatically generate calibration reports, and is equipped with a printer for on-site printing;
● The filtration system uses two-stage filtration to ensure that the equipment discharges clean air into the environment, achieving zero-pollution emissions;
● The system control uses an industrial control computer and a capacitive touch screen display, with high control precision and flexible and convenient operation;
● Using a graded generation device, the generated aerosol concentration range is wide, the precision is high, and the stability index is higher than the national standard at both high and low concentrations.

Principle
This device consists of an aerosol generator, a mixing system, a flow standard, and a concentration calibration system. It uses the aerosol generation system for quantitative supply of test particles, uses uniform dilution, diffusion, and stabilization methods for the delivery of aerosols at a set concentration, and uses an aerosol photometer mass concentration standard device (reference photometer) or filter membrane weighing method as the traceability method.
