Product Description
The Lutron GCH-2018 is a sophisticated instrument that accurately measures carbon dioxide (CO2) levels, temperature, and humidity. It uses the non-dispersive infrared (NDIR) method for CO2 detection, ensuring stability and longevity. The CO2 measurement range is 0 to 4,000 ppm, making it suitable for indoor air quality and environmental monitoring. The device also measures temperature (0-50°C) and humidity (10-95% RH). It features adjustable CO2 alarm thresholds, data hold, and max/min recording. The GCH-2018 includes RS232 and USB interfaces for data transfer. It comprises a main unit and a separate probe, both designed for portability and ease of use.
Available on EnvMart, these Air Quality Meters are built using advanced sensor technology and high-quality components to deliver precise and reliable readings. Lutron Air Quality Meters are trusted for their accuracy and durability, making them a preferred choice for monitoring environmental and industrial air quality conditions.
