The Hart Models 7007, 6054 and 6055 have extra-deep wells for use with liquid-in-glass thermometers, SPRT calibrations or other thermometry work requiring extra tank depth.
Well depth varies from 17 to 24 inches to eliminate the stem effect encountered in calibration of probes longer than 12 inches. Originally developed for a national standards lab, these baths are optimized for the visual calibration of liquid-in-glass thermometers.
The 7007 is designed for the temperature range of –5°C to 110°C, has built in refrigeration and is 24 inches deep. The 6054 covers the temperature range of 50°C to 320°C and is also 24-inches deep. The 6055 is engineered for the temperature range of 150°C to 550°C with salt and is 17 inches deep. Specific size differences and various specifications are shown in the comparison table.
The Model 6055, operating up to 550°C, uses molten salts with a pumping system for maintaining the necessary consistent fluid level required for liquid-in-glass thermometer calibrations. A viewing channel is built into the top cover for a clear visual path to your glass thermometers.
The 6055 also has the optional thermometer carousel for holding several glass thermometers in the correct calibration position without exposing the them to the hot salts in the bath. The Model 2018 Carousel is completely constructed of stainless steel and has an elevated handle for rotating your thermometers to the viewing position.
These deep-well baths are built to the same performance standards as all Hart baths, which means you can’t find another bath that has better stability or uniformity.
Don’t forget to ask about Hart’s 9938 automation software.
