Product Showcase - eNDIRi² Evaluation Kit

One of the key challenges in gas sensing today is finding a fast and flexible way to test and integrate NDIR components into measurement systems. The eNDIRi² evaluation kit from Micro-Hybrid addresses this need.

Its main objectives are to:

• Enable rapid evaluation of IR emitters and detectors
• Provide a plug-and-play setup with an intuitive GUI
• Support prototyping without requiring full hardware development
• Allow customization for specific gas applications
• Shorten time-to-market for NDIR sensors

This enables researchers, engineers, and educators to begin working with infrared gas analysis within minutes. Where traditionally, evaluating NDIR components required the development of custom electronics and software, with the eNDIRi², that complexity is removed. The system brings together modular hardware, carefully selected infrared components, and intuitive software into one integrated solution.

At the heart of the kit is the main unit, which serves as the control hub, linking seamlessly to a PC via USB-C. It supports multiple interface modules that can be connected in any configuration, offering a high degree of flexibility for different experimental setups. Paired with this hardware is a bundle of premium infrared components, including Micro-Hybrid's JSIR 350 emitters as well as high-performance thermopile and pyroelectric detectors optimized for gas measurement.

Together with the eNDIRi² App, the system makes it possible to visualize, control, and optimize measurements with minimal setup effort.

The true advantage of the eNDIRi² lies in its ability to make experimentation both faster and more flexible. Once connected, the software automatically recognizes the installed emitter and detector interfaces.

From there, users can easily adjust operational parameters such as emitter power, chopper frequency, detector gain, and offset. The oscilloscope view within the software offers real-time visualization of measurement signals across multiple channels, with options to zoom, trigger, and compare signals. More advanced users can even apply formulas directly in the app to calculate ratios between measurement and reference channels, providing immediate insight into gas absorption behavior. All data can be exported as CSV files for external analysis, while entire measuring projects can be saved and reloaded to ensure repeatable results.

The hardware itself is designed with versatility in mind. The emitter interface supports both chopper operation, required for pyroelectric detectors, and alternating polarity operation, which helps prevent drift in thermopile emitters. The thermopile and pyro interfaces amplify and digitize very low-level infrared signals, ensuring that precise data is always available. Config boards make it simple to adapt to either two-channel or four-channel detectors. To complete the setup, the included measuring cuvette provides a stable optical path for emitter and detector alignment, with gas inlet and outlet connections that allow controlled flow of test gases. For power, the system can run either from the USB port at a reduced emitter power of 500 mW, or from the included 12 V supply for full performance.
The applications for eNDIRi² are broad. In development laboratories, it allows rapid evaluation of sensor components during early-stage prototyping. In educational settings, it provides a practical and accessible way to demonstrate the principles of infrared gas spectroscopy. For industrial R&D teams, the system accelerates component selection and performance testing for gas detection systems used in environmental monitoring, process control, or safety applications. By removing the need for custom setup, the eNDIRi² frees users to focus on scientific discovery and product innovation rather than hardware integration.

From a technical perspective, the system offers the precision and adaptability needed for meaningful evaluation. The external clock input allows synchronization with custom test setups, while the autorange function automatically optimizes gain and offset for best signal resolution. Manual tuning is also available for advanced users who want maximum control. The oscilloscope functionality supports up to four channels at once, and both thermopile and pyro detectors can be evaluated under identical conditions. This flexibility ensures that users can identify the best-performing components for their intended applications.
For those looking to shorten their path from concept to prototype, the eNDIRi² is an ideal choice. It comes with everything needed to begin immediately, from detectors and emitters to software and accessories. It offers scalability as well, enabling users to expand from CO₂ evaluation to multi-gas analysis as additional components are introduced. Backed by Micro-Hybrid's dedicated support team, customers can rely on expert guidance at every step.
The eNDIRi² represents a smarter, faster, and more reliable way to engage with NDIR gas measurement. For more information, or to order your kit, visit microhybrid.com/shop
