Telaire T6615
Manufacturer-verified NDIR CO₂ sensor module.
Key Specifications
Product Positioning
Telaire T6615 is part of TELAIRE / AMPHENOL’s NDIR CO₂ sensing portfolio for OEM integration.
T6615 Dual-Channel Selection Considerations
Optical and range choice: T6615 is listed as a dual-channel NDIR device with options up to 50,000 ppm. This higher-range measurement task differs substantially from low-concentration indoor-air monitoring; match the ordered scale to actual control or process needs.
Dual-channel is not a certificate: A second optical channel may be used in the module architecture, but the term does not establish a specific accuracy, maintenance interval or safety approval. Retrieve the exact Telaire variant’s uncertainty and environmental data before final system design.
Electrical checks: The page currently identifies only a digital output. Verify communication standard, pinout, power demand and command/response expectations directly from the T6615 documentation; do not assume equivalence with T6613.
Installation: Evaluate sampling arrangement, temperature, moisture, response time, calibration strategy and the behavior of the connected controls when the measurement is above range.

Telaire T6615 — dual-reference 50,000ppm OEM NDIR family — model evidence and engineering selection
Current original manufacturer information differentiates optical design, gas span, data interfaces, revision-specific power and calibration assumptions.
| Characteristic | Source-backed detail | Selection consequence |
|---|---|---|
| NDIR hardware | One CO₂ channel and a separate optical reference channel | Different from a single optical element corrected only by fresh-air ABC. |
| Available calibrated spans | T6615 0–2,000ppm; T6615-5K 0–5,000; -10K 0–10,000; -50K 0–50,000 | The 50kppm rating belongs to a high-range order code, not every base T6615. |
| Flow-through options | Suffix -F, -5KF, -10KF and -50KF denote flow-through arrangements | A tube port/pump arrangement is ordered hardware, not an option enabled by software. |
| Reference and calibration | Dual optical channel plus three-point factory calibration process | Source drift compensation differs from T6793’s single-channel ABC scheme. |
| OEM host integration | Digital signal to external control or measurement electronics | Exact connector and output timing need the selected suffix datasheet. |
| Permanent occupation | Maker positions the unit for buildings where ABC cannot be relied on | Idealized ‘maintenance-free’ design statement does not eliminate installation check. |
| Actual applications | Indoor growing, commercial IAQ and higher-CO₂ equipment | At high percent concentrations, independent staff CO₂/O₂ safety and ventilation required. |
Firmware, operating environment and calibration
The T6615 is distinctive for CO₂-rich horticulture and permanently occupied building applications where assuming routine return to ~400ppm background may be invalid. The dual-channel optical system measures a CO₂-specific/reference ratio and producer discusses a three-point calibration strategy. The buyer must still select a T6615, -5K, -10K or -50K suffix, and a flow-through revision if using a pumped gas stream. Comparing a T6615-50K directly against T6793-5K for absolute precision without the two actual datasheets is inappropriate. Existing maker material identifies separate calibration ports and revision-specific mechanical connectors.
