Nta

• Photometer muaj peev xwm ntes tau 0.1-10 μm, 2 aerosol raws

• Siv lub tshuab hluav taws xob aerosol txias los tsim cov aerosol tsis tu ncua thiab ruaj khov, yooj yim rau kev sau cov tshuaj.

• Ntsuas aerosol concentration siv lub siab precision PM2.5 sensor.

• Los tiv thaiv kev tsim tawm ntawm tag nrho cov khoom los tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm kuaj.

• Aerosol generator: Ntsev aerosol generator LOSSIS oily aerosol generator.

• Nruab nrog aerosol particle neutralization ntaus ntawv.

• Lub pneumatic clamp yog nruab nrog cov cuab yeej tiv thaiv, uas muaj kev nyab xeeb thiab siv tau yooj yim.

• Configure kub thiab humidity sensor, real-time zaub ntawm ambient kub thiab av noo (Tub kub thiab av noo yuav tsum: 25 ℃ ± 5 ℃, 30% RH ± 10% RH).

• Nruab nrog iav rotor flowmeter, lub tshuab nqus tsev twj, laser plua plav particle txee.

• Tswj system: Lub computer tswj cov txheej txheem xeem, cia li sau cov ntaub ntawv, thiab configures ib lub computer tshwj xeeb thiab xeem software.

• Lub khoos phis tawj cia li ntsuas cov roj concentration thiab suav cov kev pom zoo. Nws tuaj yeem txuag, tso zis, nug thiab luam cov ntaub ntawv xeem.
