The ESPEC Lab Series environmental chambers are compact and reliable, suitable for a wide variety of applications. Pharmaceutical, automotive, materials, and electronic industries have all found these models to be useful for temperature/humidity testing.

To ensure a controlled environment, the LHL-113 and LHU-113 models also include an inner glass door, allowing door openings without disrupting the conditions in the chamber. A one-inch diameter cable port in the left side allows wires and cables to be run to your samples.

Easy to install and own:

• Runs on standard 115V power, enabling easy installation anywhere.
• Includes a water storage tank, avoiding the need for water hook-ups. The tank will last at least one week at 85°C/85% and can easily be refilled without interrupting the test. (Option for direct water connection.)
• Extremely quiet operation as low as 53 dba, suitable for quiet labs or offices.
