Inquiry (采购产品): VOC detector/monitor We are looking for a simple, portable VOC meter that can sense 2-4 common VOCs that may be found in homes including formaldehyde, etc and perhaps carbon monoxide as well. Can you recommend a monitor that would suit our needs? We do not require highly accurate readings, as we only intend to use them to demonstrate before and after air quality (with regard to VOC presence) of our clients' homes after they use our cleaning product. Cost-effectiveness would obviously be a major factor as we are looking at obtaining several units. To begin with, we would appreciate your pricing for 25, 50, 100 monitors. Thank you. **** Hidden Message ***** Suriana Bombalier 92673 USA Company: DFI E-mail: suriana@diamonfusion.com **** Hidden Message ***** suriana@diamonfusion.com
