The Tenney T-Shock JR is a benchtop temperature shock chamber designed for rapid thermal cycling of small components and circuit boards. This compact two-zone system delivers efficient transitions between hot and cold extremes, with a 0.25 cubic feet chamber footprint ideal for space-constrained laboratories. The unit employs a cascade refrigeration system with dual semi-hermetic compressors and low-mass nichrome wire heating elements to achieve sharp temperature ramps. Temperature uniformity maintains ±1.0°C of setpoint across the test volume.
