Moisture Meter Model AG-1

is a light weight portable instrument designed to detect moisture in food grains, pulses, oil seeds, vegetable seeds, spices and other granular substances.  The grains are compressed & conductivity noted.
It is a self contained instrument for compressing the sample to predetermined thickness and then sensing conductivity on a analoguye meter.  A thermometer is installed to take instant temperature and for easy reading of moisture percentage circular scale is given on the top of instrument.
The electrical circuit is designed for very low power consumption and it works on two small battery cells or on AC mains.
