Benchtop Controller

Benchtop Controller
Zesta’s Benchtop Controller is a precision microprocessorbased, single or dual zone temperature control panel. It is designed for today’s demanding applications that require a compact foot print, robust design and advanced features.

Simple to program, yet loaded with powerful features, the portable Benchtop Controller is small enough to take anywhere, making it ideal for most point-of-use applications.

The profiling version of the Benchtop Controller offers up to 40 automated steps, allowing flexible user programmability. Optional communications allows users to remote-configure, monitor, and/or datalog via personal computer (PC). Optional Bluetooth® connectivity allows for easy, remote configuration through the EZ-Link™ mobile app.

Custom-made Benchtop Controllers are also available. Please ask your Zesta sales representative for details.
