DHT 1500 – Digital Hand Tester
The DHT 1500 spring tester is a high-capacity / high-resolution version of our benchtop DHT (Digital Hand Tester) and can be used for tension and compression testing up to 1,500 lbf with great accuracy. The standard pull length of 18” can be increased up to 72” with optional extended rods to to test very long parts. This spring tester can also be upgraded with options like Micro-Length Adjust with length stops and USB/RS232 ports.
A two-line LED display shows force/length readings with indicator bars and features built-in deflection compensation for accurate measurements at all times. The tester is built from a rugged cast aluminum and steel frame, moves on a precision rack and pinion drive with adjustments for wear and features convenient hand operation to apply force and adjust length. It comes standard with 2 position stop rods, a standard length lock and mechanical overload stops to protect the tester from damage. The testing platforms include a 0.437″ thru-hole from the factory.
Includes Length Deflection Compensation
What is length deflection compensation?
All force/length testing devices, regardless of manufacturer, have additional deflection by the load cell and tester frame which occurs as the spring is loaded. If you buy or use a tester without deflection compensation, measurements might include significant length errors.
Spring deflection, also known as spring travel or motion, is the action of a compression spring compressing (being pushed), an extension spring extending (being pulled), or a torsion spring winding (being twisted) when a load is applied or released. This is one characteristic (spring deflection) that is measured by a Larson Systems Spring Tester.
Larson Systems has BUILT-IN Length Deflection Compensation so that the user does not have to calculate and apply length corrections. Most competitors do not have length deflection compensation.
With a Larson Systems product, forget about calculating load cell and frame deflection when testing, we’ve got you covered.
