Built-in Privacy & Security Protection
The RKI AirLink 6940NXP series AC powered ambient air multi-gas detector simultaneously uses up to four sensor elements to detect an array of gases. The Assembly reports once a minute, however the reporting rate will increase to once every five seconds if the target gases exceed a preset background level. Operates from an AC power supply with an internal backup battery pack. Magnetic switches allow for non-intrusive calibration while in the field as well as full system settings and diagnostics.
