Product Description

Contech Instruments Ltd, an ISO 9001, ISO 14001 & ISO 45001 Company established in the year 1992 is the only Indian manufacturer who has developed and manufactured in true sense the complete range of Electronic Balances from 0.01mg Analytical Balances to 50ton Crane Scales in its own setup illustrating the technical competence of the Company in the field of electronic weighing.

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 aluminum 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.

In principle, the standard weights used for the calibration of a weighing scale shall meet the metrological requirements of OIML R 111. The standard weights should not have an error greater than 1/3 of the maximum permissible error of the instrument for the applied load.

Selection of standard weights depends on weighing accuracy required for the application. The parameters to be considered are maximum capacity of the scale, least count and weighing tolerance.
