Pumped DOAS suitable for real-time monitoring of multiple parameters such as low concentration BEN/O3/NH3/VOCs/NOx

  Multi-scene application

It is suitable for real-time monitoring of multi-parameters such as low-concentration benzene/ozone/ammonia/VOCs characteristic factor benzene series (BETX)/nitrogen oxides/sulfur dioxide/formaldehyde, which integrates C/MS, GC/PID, mobile AQI air station, A multifunctional all-in-one machine with multiple instruments such as ammonia escape online monitoring device, formaldehyde analyzer, etc., can choose different application modes such as portable emergency monitoring, fixed point continuous monitoring, and vehicle navigation monitoring. DV3000 can be used as an important equipment for institutional capacity building projects such as environmental protection, safety supervision, disease control, and third-party testing.
