We calibrate testing machines up to 1,000,000lbf primarily in compression, but can do some limited tension calibration up to about 10,000lbf. We also calibrate other laboratory equipment such as small scales, load rings, load cells, linear and linear variable devices and other equipment mostly found in the Geotechnical lab. We represent most concrete testing machine manufacturers in service and consider ourselves to be the company to go to for advice on your next testing machine.
