We're based in China and as you're no doubt aware air quality here is pretty bad. We are looking to provide our clients with long term indoor air quality monitors that can log data and give real time display of PM 2.5, C02, VOC, temp and RH.
Would anyone be able to recommend a product for such application? We have head of AirAdvice and Kanomax these look good on paper but we're not sure if they will maintain sensor performance over time (we're looking to run the units constantly generating monthly IAQ reports) Most of our clients are foreign companies i.e. Disney, IBM, Fonterra etc so we do not want to sell a product that won't stand the test of time.
Any thoughts, advice, recommendations would be greatly appreciated.
