The Votsch VT4002 is a compact environmental testing chamber delivering precise temperature control from -40°C to +130°C across a 16-liter test space. Built for R&D laboratories, quality assurance, and reliability evaluation, this chamber combines rapid thermal cycling with intuitive control and remote monitoring capabilities. The unit achieves heating rates of 5.0 K/min and cooling rates of 2.5 K/min, regulated by a PID controller with single-point temperature sensing and up to 350 W heat compensation. A 32-bit S!MPAC control system drives a touch-panel interface, enabling both manual operation and programmable temperature profiles. Multiple connectivity options—Ethernet, USB, RS232, and web interface—support remote access and data logging. The EMC variant offers optimized shielding certified to 3 GHz with electrical and mechanical feedthroughs for signal integrity testing. Internal dimensions span 310 × 230 × 205 mm; the unit draws 0.7 kW at 230 V ±10%, 50 Hz, 1/N/PE and weighs 60 kg.
