Beware of counterfeit or "gray market" units advertised as "NO2 LMVV038 New." Counterfeits often use the same labeling but lack the improved humidity filter and have shorter lifespans. Always request a certificate of calibration and verification of the firmware version (v2.3 or higher for the "new" model). | | Output >20 mA (no gas) |
