CO2 monitor

CO₂ display and monitoring is becoming common to determine energy efficient ventilation regimes for buildings. The Lutron MCH-383SD is a very economical way to obtain long term data on these variables, and if desired – make a permanent display. Data is saved at intervals, or on “auto” where data is logged when there is a change in the measured variables only. The SD card can be transferred to a computer and data analysed using normal spread sheet programs. If required a USB interface and PC program for analysis is optionally available. 9VDC external power source is required for operation. The logger is only 132x80x32mm with a 50x60mm display- hanging clip supplied. The CO2 probe is separate 132x38x32mm – hanging clip supplied
  • Display and record CO2 0-4000ppm, RH 10-90% and temperature 0-50ºC
