Telaire 7001 CO2 Sensor

Contact Onset Customer Service for limited availability.



The Telaire 7001 handheld carbon dioxide sensor features patented absorption infrared technology. Each sensor measures CO2 and temperature and can calculate and display real-time ventilation rates. When combined with the HOBO MX1104, MX1105, or UX120-006M, it can record CO2. When connected to analog inputs on a HOBO H22, RX3000, or U30 series logger, it can record temperature and CO2. The Telaire comes with a power adapter, but also operates up to 70 hours on 4 AA batteries (not included). 

  • Record 0 to 2500 ppm when using the CABLE-CO2 and a HOBO U12, UX120-006M, MX1100, or ZW series logger
  • Record 0 to 4000 ppm when using the CABLE-2070 and a HOBO RX3000, H22, or U30 data logger
  • AC power adapter included
