BASICEVO from smartGAS

Diffusion sensors for ambient air monitoring are available from smartGAS as the BASICEVO series. Just like all smartGAS-sensors are distinguished by low detection limits, very slight drift, a large temperature range, a fast response time and low maintenance costs. The BASICEVO series is therefore the optimal solution for all applications in which an ambient air sensor should be reliable and at the same time simple in its handling.

The BASICEVO is a non Dispersive Infra Red (NDIR) gas sensor for ambient air monitoring using dual wavelength technology. It is designed for leak detection in small concentration ranges (ppm range) for wall mount detectors and room air monitoring devices.

BASICEVO is the perfect solution for cost-efficient ambient air monitoring – without compromises in the performance!

Versatile usability - your advantages with the EVO series!

The sensors of the EVO series are reliable, compact and powerful. Unlike many other NDIR sensors, they combine best performance with a small mechanical design. The standardized platform makes it possible to combine various EVO sensors into a complete solution in many applications. As a result, development time, storage and operating costs and not least maintenance and logistics costs can be significantly reduced.
