2 Introduction

The Kaye CTR –80 is an ultra low temp bath useful in temperature calibration and other applications requiring stable temperatures. An innovative state of the art solid-state temperature controller has been incorporated which maintains the bath temperature with extreme stability. The temperature controller uses a mi- cro-controller to execute the many operating functions.

The user interface is provided by the 8-digit LED display and four key-switches. Digital remote communications is available with an RS-232 interface.

The CTR –80 was designed to be compact and low cost without compromising performance. The CTR –80 operates over a wide temperature range from –80°C to 30°C and 50°C 100°C.
