Precision Sensing with CubiSens™ f-Series

World’s Smallest Wireless Sensor with Industry-Leading Precision

The CubiSens™ f-Series is a family of programmable and rechargeable smart loggers ideal for continuous biological and reagent process monitoring. Each CubiSens™ smart logger is fully encapsulated in bio-compatible epoxy and can be directly immersed in fluid samples, enabling rapid, direct, and spatially accurate in-situ measurement.

With unprecedented minimal form factor, CubiSens™ f-Series sensors can be deployed in small-volume fluid samples without interfering with the process environment. Measurement interval is programmable and data is stored in internal memory. After retrieval, a base station is used to wirelessly read out stored measurements and recharge the smart loggers.
