GT Granulate Flow Tester
The ERWEKA GT granulate flow tester has a special, integrated scale that can measure the weight of samples while testing their flow behaviour. Users can measure the flow time of a sample weight, a given sample volume or the flow time of a weight in a given time.
With the large full-graphic LCD and the membrane keybpad, the device can be operated comfortably. For an easy comparison, a graph is calculated, displayed/or printed (quantity/time).
- Flowability measurement by weight. (EP method)
- Flowability measurement by volume.
- Flowability measurement over a specified time.
- Determination of the flow angle with graphic representation on the printout.
GTB Granulate Flow Tester
The ERWEKA GTB is the fully equipped all-rounder in the GT family. In addition to the standard measurement of the flow properties, it has a method for fully automatic determination of the angle of repose.
For this purpose, the Pfrengle method is applied and a powder or granule cone is heaped up. The geometry of the cone is optically measured using a laser (class 2) and the angle of repose the sample is displayed as a result. The stirring unit with four speed levels is standard on the GTB.
The device is conveniently controlled via a large LC full graphic display and a membrane keypad. Two calibration cones (30° and 40°) can be optionally purchased for the calibration of the angle of repose measurement.
