Quality Assurance

Quality has been the backbone of success of Contech® over the years. All Balances are tested for quality and accuracy as per the guidelines laid down by International Organization of Legal Metrology (OIML). All Models have been approved by the Department of Weights & Measures, Ministry of Civil Supplies, Govt. of India. Company's products are supported by a team of qualified Engineers situated at various locations throughout the country. Company's customer friendly attitude and constant interactions with them has led to standardization of its products in many Industries & Institutions across the globe


Quality has been the backbone of success of Contech® 's vast experience and in depth knowledge of high precision laboratory weighing has enabled it to roll out complete range of calibration weights from 1mg to 20Kg in class E1 to M1 fully manufactured in house. The stainless steel test weights are manufactured from the finest quality material which prevents corrosion over life of weights. The weights are supplied in easy to clean sturdy and elegant aluminium or plastic boxes with protective foam material.

To obtain the best accuracy results from high precision balances, the balances need to be frequently calibrated using accurate standard weights with documented metrological traceability as required by the approved standards of internal quality assurance departments for most industries.
