S-2 CO2 Sensor (2000ppm) – With ABC

Achieve optimal conditions in your greenhouse, grow room or hydroponics farm by using the S-2 CO2 Sensor 2000ppm – With ABC. Packed with features to help you give your plants the best environment, it is able to measure CO2 concentration as well as detect light. With a range of 0ppm-2000ppm, response speed of 1 minute, and automatic calibration, you can ensure that your plants are growing in the right environment.

For added convenience, the automatic light sensor gives you the option to enable easy switching between day and night mode! If you’d rather set the sensor manually, then you can use the reliable DIP switch to set it to non-stop day mode.

Equipped with a state-of-the-art Automatic Baseline Calibration (ABC) function, which can be enabled via the extra DIP switch, any zero drift of the infrared sensor can be eliminated to ensure consistent and accurate carbon dioxide concentration measurements.

Additionally, you have the option to manually calibrate the sensor in fresh air at 400ppm by using one of our CO2 controllers.

The S-2 is fully compatible with the T-Nano, T-Micro and the T-1 Pro CO2 Controllers from Techgrow.
