DS-RF — purifier air-sampling position
The DS-RF is a low-power formaldehyde detection module for air purifiers and ventilation products. Its measuring element needs representative room air inside the equipment flow path; a sensor positioned directly after a filter or next to a chemical source may not describe the occupied room. Verify the actual sensor principle, warm-up, output interpretation and HCHO calibration from the model-specific sheet. A module photo does not substantiate finished purifier accuracy or an explosion-protection claim.
DS-RF — manufacturer model details
Formaldehyde module with additional VOC/TVOC, temperature and humidity signals. Published HCHO range 0–1 ppm, 5 ppm overload and 0.001 ppm numeric resolution; accuracy ±30 ppb or ±10% of reading, whichever is greater. Supply 4.5–7 V, T90 under 120 seconds, −40…+60°C and nominal 6-year life.
Engineering note: HCHO resolution is not overall accuracy of the complete air monitor; VOC and temperature/humidity channels need their own validation. The DS-RF data must not be replaced with DART WZ-S-K 0–2 ppm parameters.
