Warm Tips:
The instrument measures CO2 concentrations ranging from 400 to 5000 ppm. If the value exceeds 5000 ppm, "H1" will appear on the display accompanied by a continuous beep. Please power off and restart the device before resuming measurement.
Model S8601 uses a semiconductor sensor, while model S8601A is equipped with an infrared sensor. Infrared sensors offer higher sensitivity and greater measurement accuracy.
Summary
The S8606/S8601A CO2 Detector combines a carbon dioxide sensor with a temperature and humidity sensor, enabling real-time monitoring of CO2 levels, temperature, and humidity in the environment.
This device is widely used across various industries such as agriculture, aquaculture, and manufacturing. Typical applications include greenhouses, livestock farms, beer and carbonated beverage production, energy-saving and eco-friendly product manufacturing, and underground work environments.
In daily life, it is also suitable for use in kindergartens, schools, office buildings, shopping centers, supermarkets, train stations, hospitals, and other public venues. Monitoring CO2 levels in these settings helps improve air quality, which in turn enhances learning and work efficiency, prevents the spread of infectious diseases, and ensures public health and safety.

FAQs
Q1: What is the difference between the S8601 and S8601A CO₂ detectors?
S8601 uses a semiconductor sensor, while S8601A features an infrared (NDIR) sensor. The infrared sensor provides higher measurement accuracy and better long-term stability.
Q2: Why does the device beep and display “H1”?
“H1” indicates that CO₂ concentration has exceeded the upper detection limit (5000 ppm). The device will emit a continuous beep. Please power off and restart the unit before resuming measurement.
