Laboratory thermostat INTEGRAL IN 280 XT

for scientific researchprocessfloor-standing

Overview
The Integral IN 280 XT is a process thermostat with integrated refrigeration and an advanced circulation system designed for dynamic temperature control of external circuits. Operation is via the coloured TFT display on the unit or optionally via an intuitive touch operating unit; browser-based control is available through the integrated web server.
