DePS™ – Available soon

21.12.2018

The Dekati® DePS™ (Dekati® electrical Particle Sensor) is a miniature sensor for real-time particulate matter measurements. The Dekati® DePS™ allows direct monitoring of particle LDSA concentration, and the measurement signal can be easily correlated to particle number or mass concentrations. The Dekati® DePS™ is available in two versions. The DePS™-Go stand-alone version is a versatile measurement device that can be controlled and monitored both via a touch-screen display or via wireless data communication. The DePS™-OEM version consists of the particle detection and electronic control units and can be configured with a wide variety of options for optimal integration into customer-specific devices or systems.

The Dekati® DePS™ uses the same particle measurement technology as the patented Dekati® eFilter™. The aerosol sample is fed into a detector block, where the aerosol first passes through a miniature diffusion charger. After removing excess ions in the ion trap, the aerosol enters a faraday cage where a sensitive electrometer detects the charge level of the particles
at 1 Hz sampling frequency. This signal can be directly correlated with particle concentration. All units are calibrated to primary standards.
