The Cincinnati Sub-Zero ZPH-8-2-2-H/AC is a benchtop environmental test chamber delivering precise temperature and humidity control across demanding product validation, research, and development workflows. Built with a Type 304 stainless steel interior featuring heliarc-welded, continuously welded seams for hermetic integrity, the unit maintains stable environmental conditions in an 8 ft³ workspace. An air-cooled refrigeration system with environmentally friendly refrigerants supports cascade cooling for extended low-temperature performance, while the EZT-570 Touch Screen Controller with TCP/IP and serial communications enables real-time monitoring, data logging, and remote access via CSZ Connect Software.
