Moisture measuring of sand, minerals, clay, grain, foodstuffs, sawdust, ores, sewage sludge. During operation, the sensor requires nothing but a power supply and a display or a controller that can receive the measurement signal. The BMMS sensor is designed for applications in which no multi-part systems are to be used but still the highest precision is required. Due to the in-process calibration, all potential interference from the sensor installation is directly compensated for.
Hay and straw moisture and temperature meter DRAMINSKI HMM works by measuring electrical conductivity variation. HMM measures hay/straw moisture and indicates it on the LCD screen. Measured value is shown in percentage. Device can measure temperature. Has internal memory which stores last 50 measurements. Shows maximal, minimal and average values.
