Touch Screen Controller
  • CSZ EZT-570 Touch Screen Controller is designed to save chamber programming and setup time. Standard features, data logging, download files via USB, Ethernet control and monitoring, alarm notification via email or phone text message, full system security, multiple languages and more.
  • A Temperature Limit and alarm is included to protect your product.
  • Safety relay connection is provided to protect your device under test by removing power to it when the chamber is not running.
Temperature Test Chamber
  • One adjustable product shelf slides out for easier product access. Shelf design is non-tipping and supports large product loads.
  • Two, 4" (10 cm) ports are centered on the left and right side of the chamber for ease of cable routing.
  • Fog-free viewing window and interior light makes viewing workspace hassle free.
  • Leveling legs and casters are heavy duty swivel type designed for long life under heavy loading.
  • Single-handed, lockable latch and removable side panels allow for easy access to all systems.
  • Fully welded ports and shelf pilasters eliminate potential leaks, increasing the life of your chamber.
  • All liners are constructed from Type 304 brushed stainless steel that is easy to clean. All seams are continuously welded to form a hermetically sealed unit to prevent moisture migration.
  • The chamber exterior is constructed of formed sheet steel for structural strength and finished with a durable powder coat finish or textured polyurethane paint. Customer specified paint combinations are available upon request.
Reach In Test Chamber
  • Performance packages are available up to 30HP with a selection of three types of cooling systems to meet a variety of performance specifications.
  • Refrigeration design protects compressors and prolongs life keeping cool during all operating conditions. Refrigeration design uses less power, saving operating costs.
  • Pressure gauges allow operating pressures to be continuously monitored.
  • CSZ test chambers utilize refrigerants which are environmentally safe, non-flammable, non-explosive and have a Zero Ozone Depletion Potential (ODP).
  • High volume airflow system includes robust air circulator motors that provide better airflow and improves control within the chamber. Better airflow minimizes temperature gradients and accelerates temperature change rates of the device under test.
