Thinkgs to Consider when Purchasing Temperature/Humidity Chambers




		NOTE: Click here to fill in a form with your chamber requirements which will be forwarded to one of our Sales Engineers who will get back to you promptly. Items to consider when Selecting a Temperature Chamber Absolute Minimum Internal Dimensions of Temperature Chamber Required Absolute Maximum Temperature for which the chamber will be used. Absolute Minimum Temperature for which the chamber will be used. Absolute Minimum Humidity for which the chamber will be used. Absolute Maximum Humidity for which the chamber will be used. Specify Typical Temperature/Humidity Tests that will be performed. Examples: 80%RH at 80C 60%RH at 50C Even though most Temperature/Humidity chambers are specified as having a range of 20% to 98% Relative Humidity, this range is limited by a "dew point" specification which you need to know about. IMPORTANT - For further information on this, please click here. Is the Temperature Chamber going to be used for Temperature Cycling (changing Temperature automatically from one temperature to another)? If so, a programmable temperature controller will be required. Should the chamber not be used for temperature cycling,, then a single setpoint controller could be adequate (and less expensive). What Temperature Ramp Rate do you Require? For more information regarding this, please click here. If your answer to the above is Mechanical Refrigeration, do you prefer a Water Cooled, or Air Cooled System? If you prefer a Water Cooled System, do you have a Water Tower available? If you choose an Air Cooled System, would a Remote Air Cooled Condenser be Acceptable? For an explanation of the main differences between Water Cooled and Air Cooled Systems, please Click Here. What Temperature Uniformity Is Required? What Temperature Accuracy is Required? Does Product Under Test Dissipate any Heat? This is important since the chamber needs to have enough cooling capacity to overcome the Heat Load. LN2 or CO2 boost can also be used to overcome this Heat Load if necessary. What Electrical Power do you have available? What Water do you have available for Chamber Humidification (IMPORTANT)? For more information about water requirements, please click here. Will process involve any Flammable Gas or Vapors? Does Process require a Controlled Atmosphere such as Inert Nitrogen for Dry packaging of electronic components and any other application needing a protective inert atmosphere? Are any of the following options required?: Window in Door Programmable Temperature Controller Circular Chart Recorder RS-232 or IEEE-488 Data Interface Special Event Outputs from Temperature Controller Special Feed-Through Ports Castors for Easy Movement of the Chamber GN2 Purge to Prevent Condensation when Chamber is Cooled NOTE: Click here to fill in a form with your chamber requirements which will be forwarded to one of our Sales Engineers who will get back to you promptly.
