Hopper said inspection and calibration adopts two methods: one is to use standard Fa Code, this method need to spend a lot of time and manpower, and has the big difficulty.Mechanical proving ring, 2 it is, this kind of method calibration precision is low, complex calculation.In order to solve this problem, the company developed a portable dynamometer, can to each.Kind of hopper scale calibration.

Range of application：
All kinds of hopper said

Functional features：
High precision, USES the digital sensor, digital temperature compensation and nonlinear correction.
Small volume, light weight, easy to carry.
Low power consumption, the use of section 4 a battery-powered, simple maintenance.
