The DG-4 dewpoint generator can regulate the water vapor content of an air stream based on relative humidity (within 1%) or dewpoint (0.1oC). It is useful for creating accurate consistent vapor pressure or humidity profiles even in fluctuating environmental temperatures.

    The ROXY-1™ is a stand-alone universal controller.  The set point control algorithm can regulate a single variable such as oxygen, CO2, water vapor or pressure, by using the analog output of an external analyzer or fuel cell.  The ROXY-1 can create profiled or stable environments to meet diverse experimental needs for cell and tissue culture, hypoxic and hyperoxic studies, material testing and many other applications.  

The ROXY-4 universal controller is a versatile, four channel, O2 and general purpose gas controller. It can regulate many variables such as oxygen, CO2, water vapor, or pressure by using the analog output of an external analyzer or fuel cell.   Four independent channels give the flexibility to control four separate chambers or multiple variables in fewer chambers.  The set point control algorithm can create stable or profiled environments for cell cultures, material testing, hypoxia, hyperoxia, and many other applications.

The PELT-5 controller is a standalone temperature controller that drives solid-state heat pumps allowing them to regulate the temperature of practically any small object or space over the range of -5 to +65 °C, depending on configuration and ambient temperature.  The PELT-5 is designed to ramp, step, soak, or maintain a set temperature of our Pelt Cabinet, Pelt Plate, Pelt Drop-in or a customer-supplied device.  

The PTC-1 is a heating and cooling cabinet with a 30 liter capacity that is designed to be used with the Pelt-5 to create a temperature controlled environment.  The PTC-1 cabinet and PELT-5 controller is well suited for creation of field conditions in the laboratory, creating metabolism vs. temperature curves, product testing, calibration, incubation, fermentation, materials testing and other applications limited only by your imagination.
