The Refrigerated circulator 20 liter, -30°C is extremely easy to use and maintain, it combines design innovation with highly intuitive operation to deliver convenient and reliable liquid temperature control for a wide range of applications.


Set and read to 0.1°C, 170°C maximum temperature, ±0.04°C temperature stability, and a 2-speed pump make the Standard Digital Temperature Controller an economical and reliable choice for a variety of laboratory applications, including those requiring closed-loop external circulation. Cool Command™ functionality permits faster cool downs from high temperatures.

RS232 serial communication capability allows control and data logging via a PC or other remote device.

Plain-text prompts and intuitive controls guide you quickly through setup. Intelligent touch and scroll display makes it easy to make both large and small set-point adjustments.

User-settable high-temperature safety provides over-temperature and lowliquid-level protection, and adjustable high and low limits guard against unintended set-point changes.
