aChannel count includes basic pressure, temperature and humidity sensor
bChannel count is extra channels above and beyond basic pressure, temperature and humidity
cStandard configuration; frequencies can replace analog inputs
dTransmitter customized for users - options include spread spectrum modem or 403 MHz FM
†Sensors use manufacturer's calibration from part data sheet; AnaSonde-3M can be custom calibrated by the user
††Sensors are individually calibrated with NIST-traceable instruments
