CO2, temperature & humidity data logger
ESCM-212: 0 to 1% CO2 Range
ESCM-213: 0 to 30% CO2 Range
The 1% or 30% CO2 + RH/T Environmental Data Logger measures up to 1% (10,000ppm) or 30% (300,000ppm) carbon dioxide, temperature, and relative humidity levels in ambient air. It “wakes up”, take a reading, stores it in memory, and goes back to sleep until the next reading is required.
