TT Series

(500 lbf / 2.5 kN)

Spec Sheet




The CHATILLON® TT Series is a pneumatically-operated tester for measuring breaking strength of electrical leads, terminals, connectors, wire wraps, etc. It is ideal for areas where intrinsic safety is required (when used with a mechanical gauge).


The TT Series Tester operates using clean, dry air with a maximum air pressure up to 160 psig (11.2 bar). The TT Tester meets MIL-T-7928 (ASG) requirements for crimped, solderless lugs. The tester may be used for tensile or compression testing. The rapid test speed makes it ideal for production line testing, incoming inspection testing or for the R&D laboratory. The TT Tester features a 6-inch (15 cm) test stroke. Ram speed may be controlled as low as 0.1-inch (2.5 mm) per minute.


The TT Tester is available in two models: one with a foot-actuated switch; the other with a hand-actuated switch.
