CO2 transmitter INS-TR-CO2-3X9

High-concentration carbon dioxide transmitter
The INS-TR-CO2-3X9 is a CO₂ sensor for 0–100 % vol measurements, designed for industrial applications that require reliable monitoring of high volumetric CO₂ concentrations. Engineered for demanding environments, it provides stable readings for industrial processes, fermentation systems and controlled atmospheres.

Accurate volumetric CO₂ measurement
Unlike HVAC sensors expressed in ppm, the INS-TR-CO2-3X9 operates over a 0–100 % vol range, suitable for industrial contexts.

• Range: 0–100 % vol
• Resolution: ±0.2 % vol
• Accuracy: ±0.5 % vol

Easy integration into industrial systems
The transmitter integrates readily into existing architectures thanks to multiple output options and power compatibility with most PLCs and SCADA systems.

• Supply: 12–24 V DC
• Available outputs: 0–10 V, 4–20 mA, Modbus RTU

Robust design for harsh environments
Built for continuous use, this volumetric CO₂ transmitter offers:

• Enclosure rating: IP67 (excluding sensor)
• Cleanable filter to limit fouling
• Durable design for long service life
• Easy mounting to reduce installation time
