High-resolution extensometer calibrator CERH

Our model CERH high resolution digital electronic calibrator is a precise instrument designed for ease of use and rugged, long-lasting durability. Based on our model CES calibrator stand, our model CERH adds a high resolution indicator with a high quality, stand-alone, LCD display. The display's units and resolution can be easily changed and it can be run off 120 VAC or your laptop's USB port. Model CERH and Laser Interferometer This innovative design uses a digital indicator and a separate lead screw. As such, our calibrator is more accurate and not prone to read-out errors due to a sticking / dirty ball slide or excessive return spring force (unlike the micrometer head based units). This calibrator is also designed around a much stiffer frame than other brands to keep deflection errors to a minimum. The calibrator allows for easier and more accurate extensometer attachment. Its lower mounting post can be easily adjusted with the turn of a knob, while its dove-tail design keeps it in perfect alignment. For calibration of transverse extensometers, our low-profile, mounting post blocks allow closer mounting to the calibrator's center-line; reducing errors due to deflection of adapter posts. Model CERH features an easy to read, LCD display with both a units and zero button. The display can be changed from inches to millimeters with the press of a button and the zero button makes calibration easier while reducing the chance of operator error. With a full 2 inches [50 mm] of measuring range and resolution to 5 micro-inches [0.0001 mm], model CERH will meet your most demanding calibration needs.
