These units combine bath-level performance with dry-well functionality and reference thermometry creating high precision metrology wells. The analog and digital control provides stability to ±0.005C, and dual zone uniformity control function (axial or radial) is as good as ±0.02°C over a 2.4” (60 mm) zone. The built-in input accepts 100, 25, and 10Ω PRTs, and ensures reading accuracies of thermometer probes from ±0.006°C at -200°C to ±0.027°C at 661°C (not including errors from the probe).
Units feature four different pre-programmed calibration tasks that allow up to eight temperature set points with ramp and soak times between each. The large LCD display, numeric keypad, and on-screen menus are easy to read and make programming simple. The display shows the block temperature, built-in reference thermometer temperature, cutout temperature, ramp rate, and stability criteria.
Available for sale in the United States and Canada only.
