Inficon 716-701-G1 Replacement Sensor For D-Tek Carbon Dioxide CO2

Inficon 716-701-G1 CO₂ Replacement Sensor for D-TEK

The Inficon 716-701-G1 is the genuine replacement infrared sensing cell for the Inficon D-TEK CO₂ refrigerant leak detector. Designed for field replacement, it restores your detector to full factory sensitivity without sending the unit away for service.

Key Specifications

• Compatible refrigerant: R744 (CO₂)
• Sensitivity: 0.18 oz/year (5 g/year)
• Cell lifespan: Approximately 1,000 hours
• Sensor type: Infrared — highly selective to carbon dioxide, minimising false positives
• Replacement type: Field-replaceable — no tools or calibration required

Why Replace on Schedule

Infrared sensing cells do not degrade gradually — they fail. A cell past its service life may still appear to function while missing real leaks. Replacing at or before 1,000 hours ensures your D-TEK CO₂ detector maintains the sensitivity required for compliance and accurate diagnosis on R744 systems.

Important Note

All Inficon sensors are classified as consumables for manufacturer warranty purposes. Confirm your D-TEK model before ordering to ensure compatibility.
