Metrology Well, -30 to 155C, 115 VAC

Calibrate RTDs, PRTs, thermocouples, and thermistors with high-precision accuracy|Temperature range from -45 to 700C|Optional ITS-90 reference input reads PRTs to 0.006C|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 ±0.02C 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 ±0.006C at -200C to ±0.027C at 661C (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.
