Profile: Precision Measurement Co., Inc. is a manufacturer of miniature pressure transducers, load cells, extensometers, transducer and strain indicator. We serve the industries such as industry, academic institutions and research laboratories. All our transducers are fully calibrated, and calibration data is furnished with each individual instrument. Our model E 50.20 is an extensometer designed for relatively large strain levels, using a 50 mm gauge length and accepting strains up to 20 percent. This unit is ideal for teaching laboratories in materials and material properties, as it will allow strains to be read on tensile specimens without the need for expensive and time consuming strain gage application.
