The Hart Scientific 7380 is an ultra low temp bath useful in temperature calibration and other applications requiring stable temperatures. A state of the art solid-state temperature controller has been incorporated which maintains the bath temperature with extreme stability. The temperature controller uses a micro-controller to execute the many operating functions. The user interface is provided by the 8-digit LED display and four key-switches. Digital remote communication is available with an RS-232 interface. The 7380 bath operates over a wide temperature range from –80°C to 100°C.
