## Questions & Answers

**Q: Is there any way to collect data from recorder without using proprietary software?  i.e. download the csv file and sort with Excel?**
A: For a non-technical user, no. However, once the data is downloaded, I think it is in CSV format or can be exported as CSV. For a technical user, the cable is just a USB-serial interface, and when I asked EXTECH they (actually FLIR) sent me the protocol, so it shouldn't be hard to use Python or some other language to query and save data over the serial port.

**Q: Does the  extech co210 air quality carbon dioxide data logger come with a certificate of calibration?**
A: No, it does not come with calibration certificate

**Q: Hola. tiene conexión a pc o mac?. muestra gráficos en computadora?**
A: Muchas gracias por su interés en nuestros productos. Si, el modelo CO210 puede exportar los datos recolectados usando su software compatible únicamente con Windows.

**Q: Can this be used to test the quality of air from a compressor used to fill scba/scuba cylinders?**
A: Thank you so much for your interest in our products. For this special application, we recommend you to contact our Tech Support Team for you to receive the correct assistance. Please call us at 877-239-8324 Option 2 or submit a question here https://flir.custhelp.com/app/ask
