Field teams monitoring general air quality can add this module to any Base Unit build alongside other sensors.\u003c\/p\u003e\n\n\u003cp\u003eBecause the sensor reports O3 and NO2 as a combined oxidant value rather than two separate readings, operators typically pair it with a standalone NO2 module when individual ozone concentration needs to be isolated using the formula O3 equals the combined reading minus NO2. On its own, it suits general photochemical oxidant monitoring where a combined reading is sufficient.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eElectrochemical sensing: detects combined ozone and nitrogen dioxide oxidant levels.\u003c\/li\u003e\n\u003cli\u003e10 ppb detection limit: catches low level photochemical oxidant concentrations early.\u003c\/li\u003e\n\u003cli\u003e11 ppm linear range: covers trace levels through elevated oxidant events.\u003c\/li\u003e\n\u003cli\u003eUnder 45 second response: delivers readings quickly across 0 to 1ppm.\u003c\/li\u003e\n\u003cli\u003eHumidity correction: on-chip algorithm maintains accuracy across variable field conditions.\u003c\/li\u003e\n\u003cli\u003e1 ppb resolution: captures fine shifts in oxidant gas concentration.\u003c\/li\u003e\n\u003cli\u003e24 month service life: supports extended field deployment before replacement.\u003c\/li\u003e\n\u003cli\u003eSingle slot install: adds oxidant sensing without claiming the full array.\u003c\/li\u003e\n\u003cli\u003eWide humidity range: operates reliably from 15 to 85 percent RH.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe O3+NO2 Sensing Module exists to give environmental programs a way to track photochemical oxidant levels without adding a full standalone air quality station. Paired with a companion NO2 module when individual O3 data is required, it turns a single Base Unit slot into a flexible oxidant monitoring tool.\u003c\/p\u003e\n\n\u003cp\u003eChoosing between a combined oxidant reading and full O3 and NO2 separation is easier with DSLRPros technicians on the line, since we can help you decide whether a companion NO2 module fits your monitoring goals.
