LUTRON MCH‑383SD CO₂ / Humidity / Temperature Monitor  

The **LUTRON MCH‑383SD** is a professional instrument designed for precise monitoring of carbon dioxide (CO₂), humidity, and temperature. With real‑time data logging and advanced connectivity, it is widely used in industrial, environmental, and HVAC applications.  

---

Description  
The MCH‑383SD integrates CO₂, humidity, and temperature sensors into one compact system. It features a large LCD display for clear readings, user‑friendly controls, and auto power‑off to save energy. Real‑time data logging with SD card support (1 GB to 16 GB) allows seamless transfer to Excel without additional software. RS232/USB interfaces enhance data management, while alarm settings provide alerts for high CO₂ levels. Its patented design includes CO₂ height compensation for improved accuracy.
