Extra-deep wells for thermometry work requiring extra tank depth and ultimate stability

• Constant liquid levels through concentric-tube design
• Special design for sighting LIG thermometers
• Depth up to 60 cm (24 in)
• Optional interface packages control all settings

The models 6054 and 6055 have extra-deep wells for use with liquid-in-glass thermometers, SPRT calibrations, or other thermometry work requiring extra tank depth. They were originally designed for NIST.

Well depths vary from 17 to 24 inches to eliminate stem conduction effects in probes that require more than 12 inches of immersion. Originally developed for a national standards lab, these baths are optimized for the visual calibration of liquid-in-glass thermometers.
