CAL 3300

CAL 3300 Series Overview

The CAL 3300 series from Cal Controls is a family of 1/32 DIN digital temperature controllers with autotune capability. These compact panel-mount units provide precise temperature regulation and are suited to industrial process and equipment control applications.

Models in this series, including part numbers 3300, 3311, and 3322, share the common 1/32 DIN autotune base. They accept thermocouple inputs (such as Type J) and can be programmed across a wide temperature range. Their small form factor makes them practical where panel space is limited.
