In buildings where ventilation needs vary throughout the day, demand-controlled ventilation is an economical way to ensure good air quality. The Vaisala GMW115 CARBOCAP® carbon dioxide transmitter is a wall-mounted CO2 transmitter for demand-controlled ventilation. The CARBOCAP® CO2 sensors have been proven to be accurate and durable. They have an excellent long-term stability, which decreases maintenance. The superior performance of these sensors, results largely from the stable reference provided by the electrically tunable Fabry-Perot Interferometer (FPI). The tunable FPI filter provides a reference measurement and compensates effectively for any changes in the optical path. This is a unique feature to Vaisal CARBOCAP® products.

The Vaisala GMW115 transmitter is designed especially for DCV (Demand-Controlled Ventilation) applications with two optional CO2 measurement ranges of 0 to 2000ppm and 0 to 5000ppm.
