Standard Calibration Weights :
Sensortron offers standard calibration weights without or with certification from our in-house calibration laboratory which is accredited by NABL, New delhi. Organisation Internationale de Metrologic Legale (OIML, France) has classified weights in seven accuracy classes (M1 class weights,M2 class weights,M3 class weights,F2 class weights,F1 class weights,E2 class weights,E1 class weights and Slotted Weights). We offer cast iron weights, brass weights, SSweights, laboratory weights sets (1 mg - 200 g)etc.,

We also make custom built weights like slotted weights for all type of testing machines and high capacity weights ( 500 kg. IT etc) for platform scales and weigh bridges.

PRECISION STANDARD WEIGHTS
 

In all the fields of science and engineering, the research and development results are based on the precision and accurate weighing. In order to have a good weighing machine, it is important to calibrate them with a high precision weights.

Organization International de Metrology Legal ( OIML), France have classified weights in to seven categories (M1, M2, M3, F1, F2, E2 & E1). Each of the classes varies in their accuracies based on OIML Recommendations – 111 Edition 2004(E). The table of tolerances is shown in the following table.

Weights are adjusted on the apparent mass versus material of 8.0 g/cm3 density following OIML – R 111

In addition to our manufacturing capabilities, we have a commercial metrology laboratory to cater our own needs as well as the needs of our clients. The calibration laboratory adopts the ISO:IEC:17025 as per the NABL guidelines.

Apsrt from the regular weights, we also manufacture slotted weights and any custom built weights.

We also deal with Commercial cast iron weights, Avoirdupois weights, Proportional weights, Roller weights etc.,

We also undertake stamping of the commercial cast iron weights.
