Description of your image

TRUE Time-Domain Reflectometer (TDR) sensors, widely acknowledged as the pinnacle of moisture sensing technology, have long grappled with various limitations such as restricted mobility, coaxial lead connections limiting bandwidth, and steep costs, often reaching thousands of dollars.
However, Scott Anderson, the visionary founder of Acclima Inc., has revolutionized this landscape. After years of meticulous research aimed at refining and downsizing TDR technology, this year marks the unveiling of a sensor that addresses these challenges head-on. Encapsulated within a robust epoxy resin enclosure, this sensor incorporates all necessary electronics, algorithms, and signal processing, while featuring an industry-standard SDI-12 interface.
Tailored for “insertion type” soil readings, the sensor offers exceptional user-friendliness in the field. Moreover, boasting a generous 150ml sample volume, it surpasses Capacitance probes by a significant margin.
