Authentic User Feedback

🔧 Industrial HVAC Engineer Review

⭐⭐⭐⭐⭐ James Peterson - Industrial HVAC Engineer
"We’ve integrated the GRI CO₂ Module into our building automation systems across three commercial sites. The NDIR technology delivers rock-solid accuracy, and we haven’t seen any drift even after six months of continuous operation. The metal housing handles vibration and temperature swings like a champ. Calibration was a breeze thanks to the clear documentation."

🌿 Smart Greenhouse Operator Review

⭐⭐⭐⭐⭐ Elena Martinez - Sustainable Agriculture Tech
"Using the Base Model in our climate-controlled greenhouses, and it’s been a game-changer. We tied the sensor output to our ventilation and CO₂ enrichment systems, which has optimized plant growth cycles. The ±2% FS accuracy is consistent across humidity levels, and the compact size made retrofitting easy. No more guesswork on air quality!"

Purchase Date: November 2024 | Usage Period: 7 months

🚗 Automotive R&D Technician Review

⭐⭐⭐⭐⭐ David Lin - Automotive Testing Lab
"We’re using the Pro Model for cabin air quality testing in prototype vehicles. The IP67 rating and wide operating temperature range (-30°C to 70°C) are essential for our extreme-condition trials. Response time is impressively fast—under 15 seconds—so we can capture real-time CO₂ buildup during closed-circuit drives. This is the only sensor that’s held up in both desert heat and freeze chamber tests."

Purchase Date: April 2024 | Usage Period: 8 months

🏢 Smart Building Manager Review

⭐⭐⭐⭐☆ Rachel Simmons - Facility Operations, TechCorp HQ
"Deployed the Advanced Model across our office HVAC zones to automate fresh air intake. The ATEX certification gave us peace of mind for compliance, and integration with our BMS was seamless via UART. Data stability is excellent, though we did need minor firmware tweaks for protocol mapping—support was responsive and helped remotely. Would’ve been five stars with more out-of-the-box BACnet compatibility."

Purchase Date: January 2025 | Usage Period: 6 months

🔬 Research Laboratory Technician Review

⭐⭐⭐⭐⭐ Dr. Alan Wu - Environmental Research Lab
"We’re comparing indoor air dynamics in sealed environments, and the GRI module’s NIST-traceable accuracy (±1% FS on the Advanced Model) is critical for publication-grade data. It outperformed two other electrochemical sensors we tested side-by-side—zero cross-sensitivity to VOCs or humidity spikes. The modular design also lets us swap connectors when moving between test chambers."
