Exceptional Performance

Designed to provide exceptionally precise control for single set-point applications, the Performance Digital Controller delivers ±0.005° temperature stability and displays temperatures to 1/1000°. Other precision-enhancing features include 10-point calibration capability, advanced fluid tuning and remote temperature control of external applications.

Unequaled Connectivity

The Performance Digital’s extensive suite of control, data logging, and communications options make it easy to integrate into your lab’s communication platform. Connectivity capabilities include Ethernet, remote on/off, RS232, addressable RS485, and USB-A and USB-B plus command and communication protocols for other popular circulating baths. There’s even an iPhone® application that lets you check bath status or change the temperature set-point from remote locations.

Global Convenience

Icon-driven multi-language menus and contextual on-screen help guide you quickly through setup and operation. One-touch access with flexible temperature entry makes set-point changes fast and straightforward. User-settable reminders automatically alert you when routine maintenance is required.

Outstanding Safety

Over-temperature and low-liquid level protection (DIN 12876-1 Class III flammability rating), redundant over-temperature protection, high and low temperature limits and alarms provide exceptional safety and peace of mind. In addition, there’s a password protected lockout to help prevent accidental or unauthorized operational changes.
