SHEL LAB Humidity Test Cabinets provide a controlled environment for a wide range of industrial and biotechnology testing applications. This line is designed to duplicate a natural condition, which allows testing the limitations of a sample when exposed to various temperature and moisture fluctuations. Applications include: Shelf Life Testing, MIL-SPEC Packaging, Component Burn In, Vapor Transmission, Stability Testing. SHEL LAB environmental test chambers and temperature-humidity chambers provide controlled environments for a wide range of industrial testing and biotechnological testing applications. Three different chamber sizes are offered. In each size, the test chamber can be purchased with heat and humidity control only (10 deg C above ambient to 70 deg. C), or with heat, humidity and refrigeration, for temperatures from 10 deg. C to 70 deg. C. Humidity levels that can be attained depend on temperature setpoint and ambient atmosphere. Chamber liners are all stainless steel to prevent corrosion. Other features include dehumidification and flat punched stainless steel shelves.
