Polarmoist™ Optical Moisture Measurement Sensor

Accurate, Non-Contact Aggregate Moisture Measurement for Consistent Concrete Quality

Polarmoist™ is an advanced optical moisture measurement sensor designed specifically for the concrete industry. Utilizing LED and infrared technology, it provides reliable, real-time moisture readings of both fine and coarse aggregates without making physical contact with the material. By delivering precise moisture data, Polarmoist helps producers improve mix consistency, reduce waste, and enhance overall concrete quality.

Unlike traditional contact-based sensors, Polarmoist features a non-contact design with no moving parts, eliminating wear and maintenance concerns while ensuring a long service life. The system requires only a one-time calibration for each material type and can be easily integrated with virtually any batch plant control system.
