Temperature Testing Lab

GEC (Gray’s) serves as Arizona’s premiere temperature testing lab. We help clients verify whether their samples perform as expected in response to various temperatures, pressures, and humidities. Materials behave differently in different climatic conditions — metals and polymers lose their strength in extreme heat and certain ones become brittle in extreme cold, for instance. Understanding these behaviors and how they contribute to the final assembly’s performance in intended service conditions allows manufacturers to produce better products. Companies send samples to temperature testing experts like GEC to confirm their performance characteristics in response to environmental stimuli.

About Our Temperature Testing Methods

GEC’s climatics testing lab performs all our temperature testing services. Our lab personnel operate clean, modern facilities equipped with advanced temperature testing chambers. These technicians specialize in achieving precise atmospheric conditions as relevant to the testing procedure at hand. Depending on the scope of the testing requested, our technicians will perform one or more of the following methods:

Temperature Cycling

Variations in temperature can cause defects in products such as faded colors, changes in texture, or even structural warping. GEC’s temperature testing lab verifies samples’ resistance to these unwanted changes by exposing them to repeated cycles of heat and cold. Our equipment can subject samples to temperatures from 180°C to 200°C and cycle between those extremes at rates from <1°C/min to 15°C/min.

High or Low Temperature Aging

Engineers designing products for use in extreme environments, namely intense hot or cold, must verify that constituent materials hold up as required for the final assemblies’ intended purpose. To test this, our technicians expose samples to any temperature between 180°C and 200°C for extended periods. They then assess the success or failure of the sample according to the relevant testing procedures, whether standard specifications or criteria defined by the client.

Thermal Shock

Rapidly exposing a sample to wildly different temperatures one after the other can cause a failure mode called thermal shock. This may occur in its anticipated service environment — deploying from a hot boiler room into freezing waters, for instance. This phenomenon can damage the material, causing cracks that spread and undermine the structural integrity of the affected component if not properly accounted for. GEC tests materials’ resistance to this type of failure using our thermal shock units, which quickly move samples through two chambers of vastly different temperatures. Our equipment can achieve anywhere from 180°C to 200°C.


We often perform this method in conjunction with temperature cycling and sometimes altitude testing to replicate practical conditions. Exposing the sample to a humid environment can reveal its resistance or vulnerability to change resulting from moisture. Changes due to moisture can vary from electrical shorts to corrosion and material failure. The humid conditions a product must withstand can result from a moist service environment such as outdoors in a coastal city or damp shipping environments like freight by sea. Our condensing humidity chambers can maintain anywhere from 5%–99% relative humidity.


We often perform this method in conjunction with temperature cycling and sometimes humidity testing to replicate real-life conditions. Exposing samples to high pressures and atmospheric vacuums can reveal whether they are susceptible to high-altitude stress. This force can lead to progressive material failure or, in the case of explosive decompression, cause it all at once. The differing altitudes a product must withstand may result from a highly elevated service environment or shipment by air. Our altitude chambers can simulate conditions at elevations ranging from -200ft to 100,000ft.

What Sets GEC Apart

GEC values expertise and delivers quality. We regularly perform the above methods to a wide variety of testing standards and custom client specifications. Our lab maintains ISO 17025 accreditation through the A2LA to conduct these temperature testing methods to several dozen internationally recognized standards.
Companies from a variety of industries request GEC as their temperature testing lab because we offer a range of capabilities, return accurate results quickly, and prioritize their needs. Of the many we serve, the industries that most benefit from our temperature testing services include the following:
