From the maker

  • EASY-TO-USE: The color coding, prominent CO2 number on the display, and optional buzzer of this air quality meter alert you when the CO2 concentration becomes too high.
  • FREE & INTERACTIVE APP: A smartphone application for viewing and analyzing up to 90 days of historical data from your indoor air quality meter, complete with user-friendly graphs.
  • PREMIUM QUALITY: Aranet4 carbon dioxide detectors use nondispersive infrared sensor (NDIR) technology for the most precise and reliable CO2 measurements. Made in the European Union.
CO2 cylinders and pressureKeep cylinders upright and secured, and always use a CO2-rated regulator (US CO2 tanks use the CGA 320 valve fitting); never connect a cylinder straight to a keg. Store tanks cool and away from heat. CO2 displaces oxygen and collects low: ventilate, close the tank valve and leave the room if a tank leaks. Never exceed a fermenter’s or keg’s rated pressure.Source: Kegco: Everything you need to know about CO2; OSHA hazard bulletin on CO2
