MEASURING QUALITY. SINCE 1796 CIRCULATION THERMOSTATS PELTIER TEMPERATURED - SMALL AND EXTREMLY QUIET

PT80 The PT80 circulation thermostat is an extremely quiet, energy-efficient and handy device that has been specially developed for small temperature control tasks in the laboratory. Unlike classic compressor-driven thermostats, the PT80 uses modern Peltier technology to operate thermo-electrically. The environmentally friendly technology ensures extremely quiet and low-vibration operation, 50% lower energy consumption and completely eliminates the need for refrigerants. Yet rapid temperature control in a temperature range from 5 °C to 80 °C is still possible, not least due to the low...

rUJSS Optronic GmbH - PT80 Temperature DIGITAL FUNCTIONS TFT DISPLAY PT80 The easy-to-understand TFT display enables all relevant information to be clearly displayed. The temperature of the PT80 can be individually adjusted via a user-friendly touchscreen. The easily accessible functions and intuitive user guidance in the user menu ensure convenient handling. The circulation thermostat can be easily controlled with the serial RS-232 interface. This enables effective data exchange as well as remote control via PC or direct control via the user interface of our P8000 series polarimeters. PC...

The PT31 circulation thermostat is equipped with high-performance functions. The 1.5 kg lightweight device is ideally suited for applications requiring a temperature range at a constant level. The proven Peltier technology offers process-reliable temperature control in the range from 8 °C to 35 °C. The accuracy of temperature control is ±0.2 °C. The robust locking mechanism of the PT31 provides a sturdy connection and ensures constant temperature control of the medium. The compact and sturdy design does not require much space and can be placed anywhere in the laboratory. Temperature control...

CIRCULATION THERMOSTATS, APPLICATIONS AND ACCESSORIES AT A GLANCE COOLING OF CONDENSORS ON A LABORATORY SCALE Distilling links or reflux condensers are used in many thermal separation processes. On a laboratory scale, the condensers are usually cooled by tap water which is simply passed through a Liebig cooler, for example, in accordance with the counter-current principle. The cooling capacity of the flowing tap water is often adequate enough, but the water consumption of the condensers shown in the image (Lenz laboratory glass) is quite high at 70 litres per hour. The required cooling...

APPLICATION: TEMPERATURE CONTROL OF ABBE REFRACTOMETERS The PT80 and PT31 circulation thermostats are often used for the sample temperature control of refractometers, whereby the temperature control of Abbe refractometers is particularly popular. Abbe refractometers can therefore achieve highly accurate and extremely reproducible measurement results completely independent of the ambient temperatures. The more powerful PT80 guarantees fast and stable temperature control of the measurement sample even in laboratories without air-conditioning. Both circulation thermostats are extremely small...
