Integral temperature and low-liquid level protection
- Analog or digital temperature set point
- Adjustable over-temperature cutoff
- Clamp on most tanks or mount on standard lab stand
ANALOG MODEL: This low cost circulator offers great temperature control for routine lab applications. Proportional heater control combined with redundant safety backup makes this analog model an excellent value. The 2-speed pressure (simplex) pump minimizes turbulence in small tanks and provides higher flow and greater uniformity in large tanks. Temperature readout comes from a supplied non-mercury thermometer.
STANDARD MODEL: The PID microprocessor controller provides precise temperature control and greater temperature stability. Three user-defined preset buttons provide convenient access to frequently-used temperatures. The 2-speed pressure (simplex) pump minimizes turbulence in small tanks and provides higher flow with greater uniformity in large tanks. An adjustable flow director accepts 0.5-in. (13 mm) ID tubing for external circulation.
Overall dimensions of both units, W x D x H, in. (cm): 4.625 x 5.75 x 12.25 (11.7 x 14.6 x 31.2)
