Used Carlson Inspection & Metrology Equipment for Sale

The Carlson Company of Clinton, Arkansas, established itself as a specialist in spring measurement and coiling equipment, building a reputation in the wire spring industry that made the Carlson name synonymous with bench-top spring testing. The company grew by focusing narrowly on the tools spring manufacturers need most: instruments that accurately measure load, deflection, and torque, and hand coilers that let operators quickly produce prototype or small-batch springs on the shop floor.

Carlson's flagship product lines center on electronic spring testers in several configurations. The MET series covers compression and extension testing, with models such as the MET-2, MET-3, MET-4, MET-2S, and MET-400 offering capacities from 20 to 400 pounds and accuracy to 0.25 percent. The MTT series addresses torsion spring testing, measuring torque loads in inch-ounces and inch-pounds across any degree of angular deflection, while the CET and CPT series round out the range with additional compression and specialized testing options. Carlson hand spring coilers, offered as the No. 1 and No. 2 models, allow rapid manual coiling of compression, torsion, and extension springs from wire stock.

Carlson equipment serves industries where spring performance is safety- or quality-critical. Automotive parts suppliers rely on Carlson testers to verify valve springs, suspension components, and seat-mechanism springs. Aerospace and defense manufacturers use them to certify springs in actuators and control systems. General metal stamping and wire forming shops, appliance producers, and medical device manufacturers also depend on Carlson instruments to confirm that every spring leaving the line meets print specifications for load and deflection.

On the used market, Carlson spring testers are consistently sought after because of their straightforward mechanical construction, robust load cells, and the ease with which they can be recalibrated and returned to service. The instruments run on standard 110/220 VAC power, require no proprietary software, and are supported by independent calibration labs worldwide. Their compact bench-top footprint and long service life make used Carlson testers an economical choice for quality labs that need reliable spring measurement without the cost of new equipment.
