Product news

Dynament Ltd, a DwyerOmega brand, designs and manufactures non-dispersive infrared (NDIR) gas sensors for the accurate and stable measurement of carbon dioxide, hydrocarbons, nitrous oxide, and refrigerant gases.
Our carbon dioxide sensors are used across a wide range of industries, including HVAC and air quality, healthcare, horticulture, food processing, transportation, and aerospace.

NDIR technology measures gas concentration by analysing the absorption of infrared (IR) light. Each gas absorbs IR energy at a specific wavelength, creating a unique “fingerprint” that enables precise identification. The sensor determines gas concentration by comparing emitted and received IR light.
NDIR gas sensing is a proven and widely adopted method across industries such as industrial safety, environmental monitoring, HVAC, and biogas production.

Dynament’s carbon dioxide sensors are available as single-gas CO₂ sensors or dual-gas CO₂/hydrocarbon sensors, with a range of power consumption options. They are commonly integrated into gas detection and monitoring systems used in industrial safety, hazardous areas, mining, portable instrumentation, and OEM platforms requiring reliable gas measurement.

To support different integration needs, sensors are available either as raw-signal devices for customers developing their own electronics, or as fully integrated modules with built-in optics, electronics, and firmware. These provide linearised, temperature-compensated outputs. Low-power designs extend battery life in portable equipment, while dual-gas capability enables simultaneous measurement (e.g. CH₄ and CO₂) without increasing power consumption.

A range of certification options, including industrial and mining approvals, UL, and SIL1, supports use in demanding environments. Configuration tools enable straightforward set-up, calibration, parameter adjustment, data logging, and firmware updates.

We understand the importance of reliable supply and short lead times. All sensors are tested and inspected prior to shipment to ensure consistent quality.

Our engineering team provides technical support throughout product selection and integration, with access to datasheets, models, and evaluation samples.
