Product news

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

NDIR technology provides a reliable, low-maintenance method for detecting hydrocarbon gases. While sensors are typically calibrated for a specific gas such as methane or propane, the underlying principle allows detection of a broad range of hydrocarbons.

NDIR sensors measure gas concentration by detecting the absorption of infrared (IR) light. Hydrocarbon gases absorb IR energy at characteristic wavelengths, and many share similar absorption features. Due to cross-sensitivity, these sensors can detect a range of gases, including propane, methane, butane, ethylene, ethanol, and methanol, providing a flexible solution for multi-gas applications.

Our sensors are characterised during manufacturing for accurate measurement of propane (C₃H₈) in the 0–2% volume range and methane (CH₄) in 0–5% or 0–100% volume ranges. We also offer a DualGas High Resolution sensor capable of simultaneously measuring hydrocarbons and carbon dioxide in a single compact unit with the power consumption of a single sensor.

To meet integration requirements, products are available in Standard and Platinum Series formats, as well as dual-gas variants. Platinum sensors support Modbus RTU communication for straightforward integration, configuration, and diagnostics.
We provide dependable products with short lead times to support project schedules. All sensors are tested prior to shipment to ensure consistent performance.

Our engineering team offers technical guidance and development support, with access to datasheets, 2D drawings, 3D models, and evaluation samples. We also provide product customisation and branding services, with ongoing development aligned to evolving industry requirements.
