SST SprintIR-R
Manufacturer-verified NDIR CO₂ sensor module.
Key Specifications
Product Positioning
SST SprintIR-R is part of SST SENSING’s NDIR CO₂ sensing portfolio for OEM integration.
SprintIR-R: Response and Installation Verification
Concentration and range: AirAlign records the SprintIR-R within SST Sensing’s high-range NDIR CO₂ family, with options up to 100% CO₂. Specify the exact range and required response time from the current manufacturer drawing instead of assuming an arbitrary “R” suffix proves a response rating.
Serial integration: With UART listed as the interface, evaluate host update rate, electrical levels, payload handling and fail-safe behavior. If connected to an active flow or mixing process, measured delay includes gas transport, module response and controller filtering.
Comparison: The similarly named SprintIR-6S and ExplorIR-M modules require separate datasheet checks for power, size, range, temperature and calibration. Do not rely on a shared catalog heading as interchangeability evidence.
Maintenance: Plan calibration checks and easy access to the sensing path; verify accuracy and lifecycle before procurement.

SST SprintIR-R — 50 Hz CO₂ reporting, flow-conditioned fast sampling — original manufacturer selection data
SST’s OEM gas sensor specifications depend on the ordered range, gas flow, pressure and firmware. Reporting frequency, actual gas response and measurement uncertainty are distinct parameters.
| Parameter | OEM data | Engineering boundary |
|---|---|---|
| Core sensing technology | LED driven NDIR optical CO₂ with UART digital output | Measures true CO₂, not eCO₂ from a volatile-organic sensor. |
| Sampling rate | Up to 50 CO₂ readings per second according to current SST product page | Different from SprintIR-6S maximum 20 readings/s. |
| Gas test note | Maker performance statement uses 0.1 L/min sample flow and 0–10% CO₂ step | Response figures depend on flow rate; not guaranteed with arbitrary sampling tube. |
| Calibrated range options | Up to 100% CO₂ by version | Must order the selected 5/20/60/100%vol grade; low-ppm precision differs. |
| Electrical supply | Vendor describes 3.3V low-power operation | The website’s −0.3…6.0V value is the absolute supply boundary, NOT permitted operating voltage. |
| Interface | UART communication and integrated auto-calibration | No blanket assertion of analog 4–20mA, Ethernet or Modbus RS485. |
| Pressure/environment | 500mbar–2bar operating pressure according to current website; humidity below condensation | Measurement precision also depends on pressure compensation and sample state. |
| Available accessories | Optional flow adaptors, diffusion cap and T/RH-equipped variants | Only installed options support the corresponding measurement and gas path. |
Gas sampling, UART commissioning and error budget
SprintIR-R is appropriate where breathing tests or research require rapid CO₂ time series, but a 50Hz digital report is not proof that every sample changes instantaneously with actual inlet gas. SST clearly specifies the supporting 0.1L/min test flow and 0–10% gas step; track installed pump, dead volume and inlet tubing separately. The manufacturer’s web ‘Supply voltage −0.3V to +6.0V’ is an absolute rating rather than a design supply—avoid ever recommending negative-voltage powering. The 100% measurement family capability must not be conflated with low-ppm calibrated accuracy.
Original official specification: SST exact model page and linked latest technical documents. The actual range variant, test gas conditions and electrical datasheet must govern integration.
