Environmental Chamber Options

Two feed through ports, typically placed in chamber door, with protective gloves designed to reach in chamber and turn off/on test devices while chamber is in operation.

If routing cables through side ports is not an option for you, a cable notch may be placed in the front of your chamber.

Optional product shelves are available for each CSZ chamber. Custom shelves and fixtures are also available.

Control valve enhances altitude control stability at various setpoints.

For tests requiring humidity levels below 10% RH, we provide an optional low humidity system for testing down to 5% RH.

Demineralizer removes water impurities and minerals that can harm your test chamber. Cartridges will turn orange-brown when used and are easily replaceable. Additional demineralizer cartridges are available for overnight delivery.

Water pressure regulator is recommended to regulate incoming water supply to <=25 psig.

Water purification system for use with city / tap water. This option is not needed if chamber has demineralizer filter system.

Provides essential failsafe over/under (hi/low) temperature protection for your valuable test items.

A parallel interface can be provided for interface with IEEE-488 parallel instrument control buss. A standard IEEE-488 connector is provided for easy connection to adjacent test equipment. This option is cannot be used in conjunction with RS-232/RS-485 communications.

A selection of one or two pen chart recorders are available with a variety of pre-printed charts or self printing thermal charts.

The optional run time meter includes a non-resettable display which will accumulate the system running time for routine maintenance and planning purposes.

Provides an additional level of safety by shutting down the main power to the chamber prior to maintenance or repair.

Includes 15 event outputs with connection panel & removable plug connectors. Designed to turn customer’s electronic DUT’s (devices under test) ON or OFF at various stages of the customer programmed test profile. Each output may also be configured to perform other operations including alarm or profile status indicators.

Includes connection panel and 8 inputs that can be configured to perform various controller functions (i.e. start, hold, resume or terminate a profile, advance steps, control customer event outputs, etc.)

(provides 8 thermocouple / TC inputs through EZT-570i)

Designed to consist of eight (8) “T” type thermocouples (TC’s) for temperature readout with individual alarms, displays, and data logging for each input that can be monitored by the EZT-570i and the EZ-View software. The “black-box” unit itself will be mounted to the side or rear of the unit and the eight TC’s will pass through one of the existing side ports. These are TC’s only (no RH sensors or PT100-RTD’s) and are used for product temperature monitoring or temperature uniformity check within the chamber. (For monitoring only, no control.)

CSZ F4 Programmable Controller with Product Monitor, redundant high/low limit and EIA 232/485 Computer Interface. Replaces EZT-570i and mounts on a special fixture below the door.

CO2/LN2 cooled chambers are available without mechanical refrigeration for lower initial costs on applications requiring ultra low temperatures down to -184°C (-300°F). An LN2 supply tank is required with a pressure of 25 psi.

A dry air purge system can be provided to reduce condensation within the chamber and on the test item during temperature cycling testing. This option is primarily used to prevent short circuits in electronic components and is also used for low humidity requirements.

Allows the testing chamber refrigeration system to be located approximately 50 linear feet away from the chamber. This option is commonly used for labs with space restrictions or to minimize noise levels.

Although CSZ chambers are quiet operating, sound foam is available as an option to further reduce the noise generated by the refrigeration system. This option is commonly used in larger horsepower chambers.
