Old NO2 sensors were notoriously cross-sensitive to Chlorine (Cl2) and Ozone (O3). The NO2 LMVV038 New employs a chemical filter membrane that reduces cross-interference by up to 70%, ensuring you only alarm for NO2, not background oxidants.
Apply a known concentration of NO2 calibration gas (e.g., 5 ppm balance N2) at a flow rate of 0.5 L/min. Once the reading stabilizes, adjust the span pot to match the gas cylinder value. no2 lmvv038 new
Replacing your gas sensor isn't as simple as "plug and play." To ensure compliance with OSHA and NIOSH standards, follow this step-by-step guide for the NO2 LMVV038 New: Old NO2 sensors were notoriously cross-sensitive to Chlorine
