About Jung Instruments
Jung Instruments GmbH is a manufacturer of measuring and testing technology based in Viersen. Founded in 2010 by Erwin Jung, the company develops and manufactures moulding material testing devices for foundries and steelworks, dust sampling devices for occupational safety, and analysis instruments for laboratories and solids analysis. The portfolio includes, among others, the automated rammer RJ2 for specimen preparation, the strength testing devices SJ1 and WJ1, the gas permeability meter GJ1, the compactability tester CJ2, the laboratory stirrer LRW AJ1, the stationary dust collector VC 25 JI, and the BET surface meter AREA-mat. The devices are designed to deliver reproducible and operator-independent measurement results. In addition, the company offers service, calibration, repair, spare parts and loaner devices for sand testing devices, BET devices and CSONH analyzers. From Viersen, customers worldwide are served, and the company has been represented several times at trade fairs such as GIFA in Düsseldorf.

Additional services
Quality and Calibration
The devices are designed for reproducible, operator-independent measurement results; calibration is performed with DKD-calibrated measuring equipment. For dust sampling, licensed dust heads from IFA are used, and the filter condition is monitored by self-diagnostic software.
