The CO2 Monitor 4 in 1 is a portable tabletop air-quality monitoring instrument designed for real-time monitoring of carbon dioxide (CO2), temperature, humidity and TVOC. It uses NDIR sensor technology for CO2 detection, an LCD display and battery-powered operation with Micro-USB charging. 

Product Overview

The CO2 Monitor 4 in 1 is a compact environmental monitoring device intended for indoor air-quality observation. It combines CO2 monitoring with environmental parameters in a portable tabletop format.

The available product information identifies NDIR technology for CO2 measurement, LCD display, battery operation and 5V DC charging through a Micro-USB port. The product description specifically mentions real-time monitoring of CO2, temperature and humidity, while the parameter listing also references TVOC. Because the source information is inconsistent about the exact fourth parameter, the listing identifies TVOC as the fourth monitored parameter while noting that the exact display configuration should be confirmed before purchase.
