Product Description

Moisture in solids is an important parameter that influences the quality of a product and the economic efficiency of production. The HUMY 301 Moisture Meter determines the product moisture directly in the process and in real time. The measurement results can be used to control a dryer or automatic humidification and to continuously monitor the production process.
The HUMY 301 moisture detector uses a capacitive measuring method that determines the entire water content of a material – and not just its surface. To do this, the sensor’s field lines penetrate up to 200 mm deep into the material. The measurement result has an accuracy of up to 0.1 % – depending on the bulk material and measurement situation.
The latest version of the HUMY moisture meter is characterised by a robust design and easy integration and calibration. A graphical user interface for analysing the measured values, improved filter settings and the selection of up to 8 product data sets via a digital input make the user’s work easier. Long-term storage of the measurement data enables historical data to be analysed and offline calibration to be performed.
