Intuitive Touch-Screen Operation

Intuitive Touch-Screen Operation

Our icon-driven SmartTouch™ interface leads you through menus, functions and options, enabling you to make any adjustment from the most basic to the most sophisticated, even with your gloves on.

Fully Informative Display

Fully Informative Display

Our controllers display it all: internal bath temperature, external bath temperature, set-point and more. All on one easy to read screen. Our Advanced Series Temperature Controllers take it one step further — keeping critical temperature information on the display regardless of which of the many menus and functions you are accessing.

Unwavering Precision

Unwavering Precision

Behind all this innovative technology are over five decades of temperature control experience. 60 years of continual refinements to electronics, sensors, algorithms and many other elements to ensure that each and every PolyScience Temperature Controller delivers precise, reliable, and stable performance day in, day out, year after year.


Want a program to begin running while you're in a meeting? A built-in event scheduler makes it easy. Like to personalize your circulator with a favorite quote or photograph? It's as easy as putting an image on your computer desktop. No matter what you want to do, it's easier with the built-in functionality of a PolyScience SmartTouch Controller. It will even remind you when important routine maintenance is needed.

Complete Connectivity

PolyScience Temperature Controllers keep you connected to your work — from the other side of your lab or the other side of the world. Ethernet, USB-A and USB-B, RS-232, and addressable RS-485 connectivity provide multiple options for monitoring and controlling your circulator.
