Material Test/Cure Rooms


Our Materials Test and Cure Rooms offer reliable, efficient environmental controls for a variety of applications including shelf-life testing and storage, ceramic and concrete wet and dry cure regimens, thermal shock chambers, general, medical and packaging materials. All concrete curing chambers comply with ASTM standards and CCRL (The Cement and Concrete Reference Laboratory, a division of ASTM International). Some ASTM standards we conform to are C309-06, C156-05, C511-13, C666, C31, C192.

Check out our Material Test Cure Chambers for a variety of different sizes which are ideal for the rigors of precision temperature and humidity control in concrete, asphalt, and related industries.


  • Nearly unlimited Customizable options.
  • Flexible configurations/room-sizes are modular and reconfigurable.
  • Conformity with standards is assured.
  • Air flow systems are specially engineered to meet the requirement of each individual chamber.
  • With ease, our curing rooms can maintain your desired temperature and humidity, they are the ideal place for curing your cement specimens for further testing.
  • Supplied with LED lights which emit significantly more light per unit of input energy than fluorescent bulbs. They also produce less radiant heat, and with less heat used, the cooling requirement for the controlled environment is diminished and the total energy used by an LED-equipped chamber is substantially reduced.
  • Personnel emergency alarm: illuminated pull to reset push-button (inside room), control panel mounted visual and audible alarm. Includes glow in the dark label and a glow in the dark antimicrobial pull cord that can trigger alarm when pulled, a life saving feature for injured personnel lying on the floor.
