A spring tester is provided with an easily changeable and readily adjustable load cell assembly for indicating the force exerted by a spring. A second indicator provides a measurement of the deflection of a spring under a given load. In combination with the load cell assembly, means in the form of an adjustable force gage positioned intermediate the sample under test and the load cell are provided for measuring the compression or extension of a spring at a given force. Compensating means are provided for the force gage. The apparatus also includes quickly adjustable, manually operated means for measuring the force of a spring at two different compressed lengths.
