3200i Indicator and alarm unit

The Eurotherm range of 3200i indicators offer accurate indication of temperature and process measurements. Process interlocks, including overtemperature furnace limits, are implemented using relay output channels.

The emphasis is on ease of use. A simple ‘Quick Start’ code is used to configure all the functions essential for indication and protecting your process.
