EcoTechnics Evolution CO2 Analyser - NDIR CO2 Sensor for Accurate Grow Room Readings
Best for: Growers running a CO2 supplementation system who need an accurate, real-time reading of ambient CO2 levels to feed into their controller.
Our thoughts
This is the sensor that makes automated CO2 control actually accurate, rather than guessing at levels, the NDIR sensor gives a genuine reading of what's in the air. It's the piece most growers skip when they're keeping things basic, but it's what turns a regulator-and-timer setup into a properly responsive system.
The EcoTechnics Evolution CO2 Analyser uses an NDIR, non-dispersive infrared, sensor to measure the actual CO2 concentration in your growing area's air. NDIR sensing works by measuring how much infrared light is absorbed by CO2 in a sample of air, which gives a genuinely accurate reading rather than an estimate.
The analyser feeds that reading back to an EcoTechnics Evolution CO2 Controller, which then decides how often and for how long CO2 should be released from a cylinder via the Regulator, keeping levels close to your target ppm rather than drifting up and down. It's the measurement component of a three-part system, Analyser, Controller and Regulator, that together automate CO2 supplementation properly, rather than releasing gas on a fixed schedule regardless of actual levels.
How it compares
NDIR sensing is considered the accuracy benchmark for CO2 measurement, ahead of cheaper sensor technologies.
- NDIR technology gives more reliable, drift-resistant readings than the cheaper electrochemical CO2 sensors used in some budget controllers.
- Designed to integrate directly with the EcoTechnics Evolution Controller and Regulator, rather than being a standalone monitor with no automation link.
- Comparable in role to the sensors used in Titan Controls (CAP) and TrolMaster CO2 systems, which also rely on NDIR technology for accuracy.
If you're serious about keeping CO2 at a consistent target level rather than roughly in the right ballpark, an NDIR sensor like this is the accurate way to measure it.
Usage guidance
Positioning
Mount the sensor at canopy height where your plants actually are, rather than near the ceiling or floor, since CO2 concentration varies through the room.
Pairing with your controller
Connect the analyser to your EcoTechnics Evolution Controller so its readings directly drive the Regulator's release timing.
Calibration
Check and calibrate the sensor periodically as recommended in the manual, drift in any CO2 sensor over time can throw off your automated dosing if left unchecked.
Airflow considerations
Make sure the sensor isn't placed directly in a strong airflow path from a fan, which can give an artificially low reading that doesn't reflect the room as a whole.
Technical specifications
- Product type: CO2 analyser/sensor
- Sensor technology: NDIR, non-dispersive infrared
- Function: Measures ambient CO2 concentration and feeds readings to a controller
- Works with: EcoTechnics Evolution Controller and Regulator
- Use case: Accurate, automated CO2 supplementation monitoring
- Brand range: EcoTechnics Evolution
Who this is for
- Growers running a full CO2 supplementation system who want accurate readings, not estimates
- Anyone upgrading from a fixed-schedule CO2 release to genuine ppm-based automation
- Growers already using an EcoTechnics Controller and Regulator who need the missing measurement piece
- Anyone who's had inconsistent results from a cheaper, non-NDIR CO2 sensor
Our take
This is the component that makes automated CO2 control genuinely accurate rather than approximate, NDIR sensing is the technology worth having if you're investing in a controller and regulator anyway.
Pairs directly with the rest of the EcoTechnics Evolution range for a complete, properly responsive system. Proper kit at a price that makes sense for growers taking CO2 seriously.
