Analog Circulator
—Affordable and easy to use
This low-cost circulator features proportional temperature control and high-temperature and low-level cutoff. Two-speed pump minimizes turbulence in small tanks while providing greater uniformity in large tanks. Directable nozzle lets you set the direction of pump flow and accepts 13-mm ID tubing.
What's included: 5-½-ft cord with three-prong plug (240 VAC unit has standard European plug).

Digital Circulator
—PID temperature control helps avoid set point overshoot
—Two speed pump for up to 15 L/min
LED display reads temperature in °C or °F. Rapidly change set point with rotary encoder or with three user-selectable preset temperature set points. PID control ensures precise temperature under changing load conditions. Two-speed pump minimizes turbulence in small tanks while providing greater uniformity in large tanks. Directable nozzle lets you set the direction of pump flow and accepts 13-mm ID tubing.

What's included: 5-½-ft cord with three-prong plug (240 VAC unit has standard European plug).

Programmable Circulator
—Temperature stability to ±0.01°C
—Store 10 programs with up to 50 steps each
—Includes suction and pressure pump
Use this circulator for your most demanding applications. The backlit LCD simultaneously shows set point and actual fluid temperature. Displays temperature in °C or °F. Set time and temperature programs with rotary encoder. Programs can be cycled up to 999 times.
Tune the microprocessor controller to optimize PID performance for various fluids or volumes. The circulator features user-settable high and low safety limits, and overtemperature and low-liquid cutoff. Use the five-speed pump for open or closed loop applications.
Use temperature probe 12110-50 (order separately) and RS-232 interface for remote capabilities.

What's included: LabVIEW® drivers, Excel® control and datalogging macro, Palm OS® temperature control software, and a 5-½-ft cord with three-prong plug (240 VAC unit has standard European plug).
