The calibration of load cells and extensometers on materials testing instruments is our primary business objective. The amplifiers shown above are HBM MGC Plus and HBM DMP 40. These units are the most accurate in the world and are in use primarily by National Standards Organizations. These amplifiers are very expensive and for that reason are not in use by most field calibration laboratories. In order to be the best, we have invested in the best. How does HBM describe the DMP 40, “The DMP40 Digital Precision Measuring Amplifier is designed for measurement with transducers operating on the strain-gage principle. The amplifier provides stable resolution of a 2mV/V transducer signal in 1m digits. With an accuracy class of 0.0005 the DMP40 is the most accurate measurement instrument available for strain-gage measurements and can be rightly called 'the ultimate measurement tool'.”
