Compact testing for small components and products

The MicroClimate® 3 is a compact environmental chamber designed to simulate a full range of temperature and/or humidity conditions.  The small footprint of the  MicroClimate® 3 combined with temperature and humidity capabilities make this chamber the number one choice for testing small components and products.Whether you need to perform temperature cycling tests or expose your product to steady state temperature environments, these chambers will maintain precise and accurate temperature/humidity control throughout your test.

Select from your choice of six different environmental chamber models available in 115V or 230V for faster heating & cooling performance. The MC-3-1-1-HAC model now has cooling transition rates of 5ºC/min for faster cycling in a small footprint.

  • The CSZ EZT-430i Touch Screen Controller offers a choice for users to navigate like a smartphone or using windows-based navigation. Standard features include data logging, date file access with memory stick, Ethernet control and monitoring, alarm notification via email and/or phone text message, data file backup system, full system security and more.


  • 3" (8 cm) port for ease of cable routing – larger sizes available.
  • 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.
  • 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.


  • 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 and provide early warning indicators.
  • CSZ test chambers utilize refrigerants which are environmentally safe, non-flammable, non-explosive and have a Zero Ozone Depletion Potential (ODP).


  • An electronic humidity sensor is used on all humidity models for accuracy and minimal maintenance.
  • A humidity water filtration system is used to filter impurities and protect chamber interior.
