Intuitive and Precise

Our controllers display it all: internal bath temperature, external bath temperature, set-point and more–all on one easy to read screen.

Whether equipped with the entry-level controller or our most sophisticated icon-driven SmartTouch™ interface controller, PolyScience units are extremely easy to use. Clear navigational buttons and menu prompts guide you through setup, making operational and temperature set-point changes simple and precise.

Advanced Programmable temperature controllers guide you through setup and operation using universal icons, on-screen help and logical menus.

Safe and Reliable

Redundant over-temperature protection, high and low temperature limits and alarms alert you instantly to conditions that fall outside normal operating parameters. Lockout capability prevents unauthorized operational changes.

The elimination of RoHS-specified chemicals substances from fabricated components contributes to a cleaner, safer environment. In addition, all of our baths comply with WEEE, IEC 61010-1, IEC 61010-2-010, IEC 61326-1, DIN 12876 and are CE and ETL certified.

Class III Safety

Our Advanced Series Controllers feature temperature and float shut-off systems meeting DIN 12876-1 Class III standards for use with flammable liquids.


Extensive connectivity capabilities enable you to control and communicate with your circulator in a wide variety of ways, including Ethernet, RS-232, addressable RS-485, USB-A and USB-B.

Total Control
