Lutron รุ่นMCH-383SDเครื่องวัดก๊าซคาร์บอนไดออกไซด์แบบบันทึกค่าได้,3-1 Air Quality Monitor CO2,humidity,Temperature meter with DataLogging

Lutron Air Quality Monitor (MCH-383SD) Measures Carbon Dioxide CO2, Relative Humidity & Temperature. DataLogger records onto an optional SD card.

Carbon dioxide monitoring is becoming a common practice 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. Data is saved at intervals or "automatically" where data is logged when there is a change in the measured variables. Data is recorded on an optional SD card, which can then be transferred to a computer and analyzed using a typical spreadsheet program.

• Displays and records Carbon Dioxide CO2, RH and Temperature levels with date and time stamp.
• Datalogger sampling time: every 5, 10, 30, 60, 120, 300 or 600 seconds. Also can be set to automatic.
• Wall mountable & built-in easel back.
•  Large multi-parameter display.
