These accurate and reliable chambers are ideal for long-term high temperature and relative humidity (RH) testing. Designed to provide a wide range of environments, these units are suitable for both industrial and biotechnology specification testing, specifically continuous-duty projects.  All models are equipped with a gentle horizontal air flow system, which ensures stable, top-to-bottom temperature and RH uniformity. Low temperature models 9005L and 9010L feature CFC-free refrigerant. Relative humidity range may vary depending on temperature set point.  Digitally set, microprocessor temperature and humidity controllers allow precise setting with direct digital read-out in degrees and percentage RH.  The over-temperature safety control prevents possible damage to samples or equipment. A vapor generator compresses moisture and injects it into the chamber to provide controlled humidification. Automatic water level control maintains liquid level in humidity reservoir. Pressure coupling allows for easy hook-up of in-line plumbing or a carboy of distilled water. All units feature interior drain.
