Carbon Dioxide Data Logger with Wide Temperature and RH Range

Carbon Dioxide Data Logger with Wide Temperature and RH Range



TandD Logger Measuring and Recording Carbon Dioxide, Temperature and Humidity


  • Measures and Records Carbon Dioxide (CO2), Temperature and Humidity in Indoor Environments
  • 0 to 5,000 ppm (CO2), -30°C to 80°C (Temp) and 0 to 999% RH (Humidity) Measurement Ranges
  • Programmable Alarms and Contact Closure Output
  • Large LCD Display will Cycle Through all Three Measurements
  • Perfect for Air Quality Monitoring and IAQ Auditing
