I'm looking for a Duct CO2 Transmitter that also measures temperature and relative humidity. It's crucial that the device performs accurately and reliably, as it will be used in environments where precise monitoring of air quality is essential. I'm interested in discussing the specifications, features, and price range of your available models. Additionally, could you provide details on the expected lead times for delivery and any volume discounts you might offer? It would also be helpful to know about warranty options and technical support available after purchase. Let me know if you have product datasheets or catalogs that I can review. Looking forward to your prompt response!
