EziLab refrigerated circulator bath EZL-RB151 provides precise temperature control from -20°C to 200°C across a 9L stainless steel chamber for laboratory processes requiring both heating and cooling. A PT-100 temperature sensor ensures accurate temperature monitoring for consistent performance throughout operation. The integrated air-cooled refrigeration system enables efficient cooling cycles, while the circulation pump maintains uniform temperature distribution throughout the bath. A digital PID controller allows precise setpoint adjustment for controlled operation across varied applications. Designed for reliable use in continuous laboratory workflows without interruption. Suited to petroleum testing, calibration tasks, materials testing, quality control, and laboratory process temperature control.
