Model CESH - High Resolution Extensometer Calibrator

A high resolution calibrator for fast and accurate calibration of your extensometers.

Our model CESH 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 CESH 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.

This patent pending 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 CESH 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 CESH will meet your most demanding calibration needs.

Our calibrator comes with either Ø3/8 inch [9.52 mm] or Ø1/4 inch [6.35 mm] smooth, round, adapters.  In addition, a vast array of adapters are available for calibrating transverse, diametral, and Clip-On gages.

Each calibrator is supplied with an inspection certificate traceable to NIST and a rugged, foam lined, storage case.
