Laboratory thermostat Integral IN 280 XTW

for scientific researchprocesson casters

Overview
The Integral IN 280 XTW is a circulation process thermostat with integrated cooling designed for dynamic temperature control of external circuits and heat-transfer media. Operation is via a coloured TFT display on the unit or an optional touch operating unit; network control is available via built-in web server and standard interfaces.

Key features

• Process thermostat with integrated cooling system for dynamic control of external circuits
