Product Details
The indoor air quality meter measures and records carbon dioxide (CO2), temperature, and humidity, featuring a high-resolution color TFT touchscreen display and user-selectable recording times. The R9920 includes a programmable alarm set point, a built-in desk stand, and a wall mounting bracket, allowing for versatile placement. This device simultaneously monitors CO2, temperature, and relative humidity with a low-drift NDIR CO2 sensor for stable and accurate readings. It offers a user-selectable unit of measure (°C or °F) with a 7" (178mm) display at 1024 x 600 pixel resolution. The meter includes adjustable high and low alarms, a maximum/minimum display, and an internal 16GB memory that stores data points in CSV format. Users can select a sampling rate ranging from 1 second to 24 hours, with an internal time and date stamp. It operates on a rechargeable Li-ion battery and comes with a low battery indicator, a USB cable of 10' (3m) length, and operates effectively in temperatures ranging from 14 to 104°F (10 to 40°C) with a humidity range of 0 to 100%. The maximum operating altitude is 6561' (2000m). The kit includes the indoor air quality meter, USB cable, power adapter, and wall mounting bracket, making it suitable for environmental monitoring in schools, office buildings, greenhouses, factories, hotels, hospitals, and laboratories, particularly in areas where high levels of carbon dioxide must be measured.
