The Dekati® DePS™-Go (Dekati® electrical Particle Sensor) is a miniature sensor for real-time particulate matter measurements. The Dekati® DePS™-Go allows direct monitoring of particle LDSA concentration, and the measurement signal can be easily correlated to particle number or mass concentrations. DePS™-Go  is a versatile, stand-alone measurement device that can be controlled and monitored either via a touch-screen display or via external I/O data communication. The measurement data can be saved to a SD-card or transmitted via an USB port. Power is provided via a built-in battery or via the USB-power socket. As such, the Dekati® DePS™-GO is perfectly suitable as a portable or as a stand-alone measurement tool.

Dekati® DePS™-Go uses the same particle measurement technology as the patented Dekati® eFilter™. The aerosol sample is fed into a removable detector module, 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 and all units are calibrated to primary standards.

DePS™-Go is available until the end of 2021.
