泰国采购需求：自动菌落计数器，气溶胶光度计，THC分析仪FID，尘埃粒子计数器

I'm reaching out from Inctech Metrological Center in Thailand. We're looking for an effective air capture hood designed specifically for measuring airflow in Biosafety Cabinets (BSC). Any recommendations you have for suitable models would be greatly appreciated. I'd prefer to communicate via email for this inquiry, as I feel more comfortable expressing myself in writing rather than speaking due to my limited fluency in English. Thanks for your understanding, and I look forward to your suggestions!
