新加坡采购需求：多传感器空气质量监测器、产品和解决方案

I'm interested in sourcing an Indoor Air Quality (IAQ) meter that comprehensively measures several key parameters: CO2, CO, TVOC, formaldehyde, air temperature, relative humidity, air velocity, and particle counts for PM2.5, RSP, and PM10. Could you provide me with detailed specifications, pricing, and lead times for your available models? Additionally, I would appreciate any information on certifications or testing standards they comply with, as this is crucial for our quality assurance process. Looking forward to your prompt response!
