Product Category Description:

The Optima Series immersion circulators offer a wide range of circulator options from analog units to programmable digital models. The models work with Boekel's S Series stainless steel (see 47727-824 series) and P Series plastic tanks (47727-834 series).

The analog circulators feature a low liquid level float switch, a simple dial setting, and a visual liquid level alarm. All digital circulators feature microprocessor control, low liquid level float switch, a 4-character digital display, an operating setpoint plus three preset temperature valves, a visual liquid level alarm, and two point calibration. The high performance digital circulators also feature a reaction timer, a high/low temperature alarm, a dual display (4-character LED plus two-line 16-character LCD), an on/off heater timer, RS-232 interface, offset adjustment, and compatibility with Labwise* software. The high performance circulators have stored program capacity of one program for GR150 models and five programs for GP200 models.

The "K" version of the circulators feature the K clamp (47727-820) that may be used with circular tanks with a maximum wall thickness of 2.5cm and a diameter of 15.25cm (6"); circular tanks with a maximum wall thickness of 3cm and a diameter of 30.5cm (12"); and rectangular tanks with a maximum wall thickness of 3.5cm.

The Labwise software (47727-822), used with GR150 and GP200 model circulators, features real-time status windows, a graphic display of the program's performance when running and allows data to be logged for future recall and analysis. The set-up features set temperature, high and low alarms, reaction timer, and delayed start and stop time. Program values may be set graphically or numerically for up to 30 segments per program. The software also controls pump speed for GP200 models.

Ordering Information: All immersion circulators come with manufacturer's three-year warranty on parts and labor. Accessories sold separately.
