Optimized
The Advanced Digital Temperature Controller displays and controls bath temperatures with ±0.01°C precision and stability. Plus you can further optimize performance through a variety of control settings including pump speed, specific heat value, calibration offset and internal or external temperature control.
Communicative
Bi-directional RS-232, addressable RS-485 and Ethernet communications provide fast and versatile remote control and data logging. USB-A and USB-B enable you to log data directly to a flash drive or computer.
Friendly
On-screen prompts and 4 languages (English, Spanish, French and German) take the guesswork out of setup and operation. Adjusting the temperature set-point, pump speed or other operational settings is simple, straightforward and intuitive. In addition, the Advanced Digital Temperature Controller features a message bar that assists in making changes and provides alerts and safety information.
Safe
The Advanced Digital Temperature Controller delivers exceptional safety for a wide variety of laboratory applications. Standard safety features include redundant over-temperature protection, low-liquid level float switch, user-settable over-temperature safety and high and low temperature limits.
