Get real-time leakage monitoring of your plant with a single, multi-gas microchip

Introducing EnviCam®-3x-COG, a revolutionary multi-gas microsensor that enables petrochemical plants to ensure the safety and health of their employees and to comply with environmental standards. In combination with our self-calibration algorithms, they are also reducing their maintenance costs.
EnviCam-30 microsensor


The petrochemical industry is in demand for solutions to precisely measure ambient gases, aiming to minimize environmental impact and ensure effective leakage control.

At the same time, the industry seeks solutions that seamlessly integrate with their current systems, while also contributing in optimizing operational costs.

How EnviCam-3x COG helps improve gas monitoring processes

High selectivity

with respect to the chemical compounds of interest (ammonia, nitrogen dioxide, methane, carbon monoxide...)

Ease of integration

Small size, small amounts of external components (low BoM cost), algorithms internal or external to the device




Long operating lifetime
  • Ultra-low-power consumption
    < 10 µW @ 1 measurement per second (per sensing element)
  • High autonomy > 5 years with self-calibration algorithms
