These appear to be new old stock. The boxes have been opened, however the terminal blocks and mounting holes appear to be unused. While we don't have the capability to fully test/calibrate these units we did power them up and let them run for several days while trending the output value, which seems to track quite closely compared to a known-good CO2 sensor. While these are being sold as-is we will honor a 14-day non-DOA warranty (exchange for another sensor).
