Application area: mining-concentrating combines, mines, careers, geophysical parties, Technical Control Departments, geological survey, protection relay against phase loss.

Operating principle - measurement made to the inductive impedance converter, which characterizes magnetic permeability of the ore.

Device calibration is made in one or more reference samples.

Period of guarantee is 12 months.

It is not required special sample preparation.

NOTE:

*- Inductive, invoice with axially symmetric field, parametric, with variable geometry;

** - Inductive, parametric, with suppression of influence segregation processes in the pulp.

***- With a confidence level of 0.95 (depending on the ore species).
