This unit is a grain moisture tester that applies electric resistance of an object to be measured.
Only putting the bar sensor into bag displays their moisture content (%). This moisture
tester needs only simple operation for quick measurement without selecting an operator or
measurement environment.
• Bias adjustment for moisture values
Bias adjustment for moisture values in the range from -9.9 to +9.9% with respect to each
calibration curve.
• Can create a maximum of 10 user calibration curves (scaled)
Users can record their own calibration curves to support various types of jute.
• Auto power o
If no measurement is made or key is operated for approximately 5 minutes, the power is
automatically shut o and avoids wasting the batteries.
• Other functions
Average value, upper limit setting, data storage (max. 250), company name setting, date and time
setting are available. An optional printer and PC software for data logging are also available.
